On this page, you’ll find information about major studies, planning efforts, and construction projects currently underway in DOTI.
The City and County of Denver is working to establish a future vision for the Alameda Underpass near the Baker, Valverde and Athmar Park neighborhoods and the Alameda transit station.
We have conducted a comprehensive study of the Alameda Underpass between Santa Fe Drive and Cherokee Street to establish a multi-modal vision for the Alameda Underpass area and help plan for the implementation of improvements and design of the underpass. The project identifies benefits and challenges of various ways the City might address the corridor’s identified needs, and vets those options with very preliminary conceptual design.
The project’s final Conceptual Study Report was released in May 2019. It identified a preferred roadway cross-section alternative and helped plan for the future, potentially phased implementation of these improvements.
The City and County of Denver is transforming a stretch of Bannock Street from 14th Avenue to Colfax Avenue into a versatile public gathering space that people on foot and on bikes can enjoy year-round and experience as a new gateway to Civic Center Park.
Bannock Street, which borders Denver’s iconic Civic Center Park has primarily served to move vehicle traffic for many years. Now, the goal is to bring Bannock Street itself into prominence, as a space to be enjoyed and celebrated, and serve as the front porch of Denver City Hall.
The Bannock Street Project is located between 14th Ave and Colfax Avenue.
The Bannock Street Project will unfold in two phases. On April 21, as part of Phase 1, Denver’s Department of Transportation and Infrastructure (DOTI) will close Bannock Street between Colfax Ave and 14th Avenue to vehicle traffic and reopen the stretch to the public in mid-May with tree planters and a colorful street mural.
The Brighton Boulevard Redevelopment Project designed and constructed critical public infrastructure (e.g. cycle track, sidewalks, curb/gutter, on-street parking and more) on Brighton Boulevard, helping establish Brighton as a gateway to Denver.
Work on the first two segments, from 29th Street to 44th Street, began in Fall 2016 and was substantially completed in 2019.
The initial vision was developed in 2014, followed by a planning process with stakeholders to determine key elements for the design.
Colfax Corridor Connections is a project that is studying mobility needs and identifying transit and other multimodal improvements, including bicycle, pedestrian and vehicular, within the East Colfax travel corridor. The corridor is roughly bounded by I-25 and I-225 to the west and east, respectively, and by 12th Avenue and 20th Avenue on the south and north.
Since 2015, Department of Transportation and Infrastructure (DOTI) has been studying Broadway to make the corridor safer for bicyclists, drivers, pedestrians and transit riders.
In 2019, after extensive community input and technical planning, the City is designing a more multi-modal Broadway:
Transit improvements: Following initial transit improvements along the Broadway/Lincoln corridor, DOTI plans to extend transit-only lane hours on South Lincoln Street. During the planning phase, the project team is seeking input from the community on the preferred alternative for Lincoln from I-25 to 7th Avenue.
Denver Moves: Downtown is a planning effort that is re-envisioning the city’s downtown transportation system. It will build off years of study and analysis to create a roadmap for implementing tangible near-term improvements that the hundreds of thousands of people who live, work, study, visit and play in downtown Denver will experience in the coming years, while also identifying a long-term vision for the future of mobility in the city’s center.
The effort is being led by the City and County of Denver, in collaboration with the Regional Transportation District and the Downtown Denver Partnership, and will be completed in early 2020.
A public meeting that was supposed to occur March 25 has been postponed to June 10. Attend this open house to learn about the proposed future improvements for getting around on downtown streets:
The transit study and alternatives analysis will advance the corridor vision by identifying and analyzing transit options along the corridor, and examining how enhanced transit can better serve the communities that make this corridor such a vibrant and multi-faceted place.
The 2017 Federal Boulevard Corridor Study outlined a vision for a well-connected multimodal and high capacity Boulevard that supports and celebrates diverse local business, residents, cultures, natural resources and community. Traveling the corridor will be safe, easy, and comfortable for all modes of transportation.
The next step in the planning process is to evaluate costs, benefits, and impacts of potential transit options. Building on a combination of multiple past and ongoing mobility, land use, and community studies, the project team will work with stakeholders to select a range of potential options for high capacity transit on Federal Boulevard from Floyd Avenue to 52nd Avenue.
Denver’s Department of Transportation and Infrastructure (DOTI) has nearly completed improvements to Federal Boulevard between West 5th Avenue and Howard Place to improve safety and operations for multimodal travel. Preliminary design began in 2011, following the vision established in the city's Federal Boulevard Corridor Plan in 1995 and a study of Federal Boulevard between 5th Avenue and Howard Place.
The City and County of Denver is improving the experience for people walking along and near Federal Blvd between W 23rd Ave and 27th Ave. This project is funded through the voter-approved Elevate Denver Bond Program.
Join us at our second community open house to learn about and help prioritize possible improvements the City could make in the area as part of this project.
Your feedback will help us plan and design this part of Federal Blvd to meet community needs, increase safety, and benefit all.
The city conducted a corridor study in 2018-19 to recommend multimodal and placemaking improvements for Hampden Avenue.
Denver voters approved funds through the Elevate Denver Bond Program to fund Hampden Corridor Multimodal Improvements.
Mississippi/Parker — Status: Construction Procurement
This project will provide a continuous multi-use trail bypassing the busy intersection of Mississippi Avenue and Parker Road by building an underpass beneath the road. Final design was completed in summer 2019. Construction procurement is underway and construction is expected to begin early fall 2020.
Colorado/Hampden — Status: Construction Procurement
This project will provide a continuous multi-use trail bypassing the busy intersection of Hampden Avenue and Colorado Boulevard by building two underpasses beneath these two major arterials. Final design was completed in 2019 and construction is expected to begin in Spring 2020.
The City and County of Denver will provide pedestrians and bicyclists with a safe, comfortable, intuitive connection underneath the railroad tracks heading east to the South Platte River Trail.
The fully funded project will remove the stairs to create an ADA accessible, separated path. This new ADA compliant facility will eliminate the gap along the D18 bike route providing increased safety, clearer wayfinding, and an improved user experience. The project will also include improved crossings at Santa Fe Drive and a new sidewalk offset from Santa Fe Drive, spanning Jewell Avenue to Florida Avenue.
The Iowa Underpass project will be split into two phases, Santa Fe and the intersection, and Iowa. Advertisement for construction for Santa Fe is scheduled for late 2020, with Iowa to follow soon after.
This project will involve a 1.1 mile extension of Martin Luther King Jr. Boulevard (MLK) from Havana Street east to Peoria Street within the Stapleton Redevelopment Area. The new roadway will include travel and parking lane changes, multi-use paths for bicycles and pedestrians, a soft-surface equestrian trail, and new signals and street lighting.
Construction is scheduled to begin November 19, 2018 and will continue through July 2020.
Denver’s Department of Transportation and Infrastructure (DOTI) will redesign Peoria Street to add multimodal connectivity from E 37th Avenue to E 56th Avenue and address safety concerns at several intersections. The first phase will provide new sidewalk and a multi-use path where there are currently sidewalk gaps immediately north and south of planned improvements by CDOT at Interstate 70. In the second phase of the project, the city will design a pedestrian and bike path on the east side of the roadway on Peoria, improved sidewalk on the west side of the roadway, and safer crossings at certain intersections to provide improved north-south multimodal connection for the Montbello neighborhood.
The City and County of Denver and Department of Transportation and Infrastructure (DOTI) is working to identify, design, and develop pilot streetscape improvements for the Santa Fe Corridor between 8th Avenue and West Colfax Avenue. Santa Fe Drive is an important corridor within the Denver transportation network. It is a key link between downtown, 6th and 8th Avenues, and I-25, providing connections for a variety of users in the neighborhood and the greater community.
While the piloting of an enhanced streetscape is the primary focus of this design study, it is also an opportunity to evaluate the Santa Fe corridor for a longer-term vision.
The Sheridan Blvd. and 52nd Avenue Pedestrian Safety Improvement project, which spans multiple jurisdictions, will take the first steps to identify and evaluate the safety and infrastructure issues within the project area. The project area is defined along Sheridan Blvd. as approximately the area between the intersections of Sheridan Blvd. and West 48th Ave. on the south and Sheridan Blvd. and 52nd Ave. on the north. Along West 52nd Ave., the project area is approximately the area between the intersections of 52nd Ave. and Lowell Blvd on the east and 52nd Ave. and Jay Street on the west.
The project will evaluate and may provide preliminary designs for improvements which include:
The project will provide preliminary plans and project cost estimates by December 2020 to inform jurisdictional stakeholders and facilitate funding discussions for future final design and construction projects.
The City and County of Denver's planned improvements along South Broadway corridor and at the I-25 Interchange aim to create a corridor that provides safe and efficient mobility for all transportation modes (pedestrian, bicycle, transit, and automobile); promote transit-oriented development; and to accommodate the existing, future and planned developments along the South Broadway corridor.
The City and County of Denver, in coordination with the Globeville community, conducted a two-year study of the Washington Street corridor that concluded in 2018. The study recommended redesigning Washington Street to support the community’s vision for a mixed-use riverfront destination that capitalizes on its proximity to the South Platte River and National Western Center.
Beginning in 2019, the city will begin the design phase on Washington Street:
The Walnut Street Corridor Improvement project, headed by Denver’s Department of Transportation and Infrastructure (DOTI) and the North Denver Cornerstone Collaborative (NDCC) will study the traffic and safety needs for this corridor and assess the possibility of a two-way conversion.
Phase I improvements, to define parking and walking spaces on Walnut from Broadway to 36th Street, were completed in Summer 2017.
The Phase 2 study report was completed in 2019, with plans to identify funding to convert Walnut Street to two-way travel between Broadway and Downing with updated signage and restriping, in order to quickly meet safety needs. The long-term recommendations of the study call for rebuilding the corridor from Broadway to 36thStreet, including sidewalks, curbs and gutters.
The West Colfax Pedestrian Safety and Transit Improvements Project will construct roadway modifications between Sheridan and Irving Streets to improve the overall safety of the corridor for pedestrians. Additionally, the project will construct improvements that benefit the speed and reliability of transit service on the corridor.
West Colfax Avenue was identified as a part of the high-injury network in the Vision Zero Action Plan. The high-injury network contains corridors with the highest percentage or serious injuries or fatal crashes. The pedestrian safety improvements are aimed to reduce crashes on the corridor and improve safety.
In 2017, Denver voters approved of funds in the Elevate Denver Bond to be used for pedestrian crossing improvements to West Colfax, as well as improving the efficiency and reliability of transit along the corridor. Transit improvements may include modifications to traffic signals and bus stops to support transit operations. Examples of pedestrian crossing improvements could include medians, curb extensions, and enhanced crossings that improve safety at intersections.
The West Colfax and Villa Park neighborhoods were selected as the next two neighborhoods to go through the NTMP Action Plan collaboration process. The West Colfax and Villa Park neighborhoods are just west of downtown Denver, spanning from Federal Blvd to the east, Sheridan Blvd to the west, 17th Ave/19th Ave to the north, and 6th Ave to the south.
The West Colfax and Villa Park NTMP will be coordinated with City and County of Denver mobility projects underway in the neighborhoods, including multimodal improvements as part of the city's bike implementation program, and the West Neighborhood Planning Initiative (NPI).
Department of Transportation and Infrastructure (DOTI) is studying the East Yale Avenue Corridor from Franklin Street in the west to the High Line Canal trail connection at the city limits, coordinating with the community to explore potential projects along the corridor that would improve conditions for everyone walking, bicycling, taking transit and driving.
The study will begin in 2019 with an existing conditions assessment and will conclude in 2020 with recommendations for future actions.
The I-25 & Belleview Avenue Interchange Improvement Study is examining several possible improvements for the interchange of the South I-25 Corridor and Belleview Avenue between Monaco Street and DTC Boulevard. The purpose of the proposed improvements is to address growing levels of traffic congestion; user safety, and lack of multimodal choices and connectivity.
The City and County of Denver is a partner in this study with the City of Greenwood Village, Arapahoe County and the Southeast Metropolitan Public Improvement District (SPIMD).
Changes were made on 15th & 17th Streets to better organize the roadway so that people who walk or roll, bike, take transit, and drive have dedicated space to travel safely and more predictably. The improvements have increased the comfort, safety, and convenience of walking or rolling, biking, and transit as travel options:
This comprehensive study will develop a community-facing infrastructure plan for the north Denver community, creating a hub of vibrant land use at the 41st and Fox Station Area. It is a joint effort of Denver Community Planning and Development, Public Works, and the North Denver Cornerstone Collaborative.
The project comprises the design and construction of a bicycle and pedestrian bridge with stairs and ramps crossing over the Union Pacific railroad line, south of the existing crossing at 47th Avenue and York Street. Design will conclude in 2018, with construction expected to take place in 2019.
This location was identified in the Elyria Swansea at York - East/West Connectivity Study conducted in 2016 to evaluate multi-modal connectivity in Elyria Swansea and improvements in the area north of I-70 and south of 49th Avenue.
Denver’s Department of Transportation and Infrastructure (DOTI) is making improvements to 56th Avenue across the Peña Transportation Corridor, from Memphis Street east to approximately 400 feet east of the Regional Transportation District (RTD) A-Line rail bridge, to improve traffic operations and safety of the interchange, address future travel demand, and enhance multimodal use and connectivity.
Environmental clearance and final design were completed in 2019. Construction is currently underway.
This pilot program is part of a larger city initiative to meet needs for publicly accessible restrooms in the central part of the City. In addition to mobile restroom facilities that can be moved to serve select activities and areas, the City is also reactivating existing facilities at parks and public sites.
Department of Transportation and Infrastructure (DOTI) repairs and improves public streets with services that include paving, pothole patching, curb and gutter repairs, and curb ramp installation, as well as maintenance tasks such as street sweeping and snow removal.
Denver is taking a comprehensive approach to better protecting people and property against flooding while improving water quality and enhancing public spaces. The Platte to Park Hill: Stormwater Systems program is focused in the near-term on the northern neighborhoods of Elyria, Swansea, Cole, Clayton, Skyland, Whittier, Five Points and Northwest Park Hill. The City began planning this phased effort in Summer 2015.
The 27th Street Storm Drain is one of several large diameter storm drain projects that the City and County of Denver has identified to improve public safety by relieving drainage and flooding issues in the Curtis Park and Five Points neighborhoods. The 27th Street Storm Drain project includes approximately 5,900 linear feet of large storm pipe ranging in size from 78 inches to 96 inches in diameter.
Phase 1 construction was completed in summer 2019. Construction is expected to begin on Phase 2 in late 2019 or early 2020.
Denver is installing a new storm sewer system in the Curtis Park neighborhood to provide 5-year storm protection to residents and businesses in the area and important drainage improvement around RTD’s East Rail Line. Five Points, Whittier, and City Park West neighborhoods are also situated in these drainage basins.
Storm drain construction starts at the South Platte River progressing uphill in 33rd Street, crossing the Downing Street intersection and continuing upstream in Martin Luther King Boulevard from Downing Street to Lafayette Street.
The first several phases were completed from 2016 through 2018. Phase 4 construction was completed in December 2019.
The City and County of Denver is making improvements to the existing 38th & Holly Detention Pond. During small and larger storm events, water collects in Holly Street at depths up to approximately 1.5 feet. The water then overtops the pond embankment along Holly Street to enter the pond and causes severe erosion to the embankment, creating on-going maintenance concerns and repairs.
The project will construct a new rundown to prevent future erosion, provide stormwater quality, and significantly re-landscape the detention pond and plant trees for pedestrian shade. When the improvements are complete, the project will safely direct stormwater into the detention pond while improving the water quality and the aesthetics for the surrounding neighborhood.
Construction is beginning in Fall 2018.
The East 16th Avenue Storm Interceptor project area is located in Montclair Basin, to address flooding of the neighborhood. Existing storm sewers in East 16th Avenue and Batavia Place are currently undersized; this project's goal is to work with hydrology developed by the Outfall Systems Plan (OSP) team to size, design, and construct a new storm main line to safely transport the flows from existing systems in Colfax Avenue and East 16th Avenue towards City Park, while picking up the local flows along the way.
Plan development is expected to be complete in late 2019, with construction to be determined following the final design.
The Ellsworth Avenue Storm Project is a key project identified in the City & County of Denver Storm Drainage Master Plan to relieve historic drainage problems in the Cherry Creek East neighborhood and reduce flows into the Cherry Creek business district. This project’s goal is to collect flows at low-lying intersections located between Garfield Street and Steele Street which currently flood both in summer and winter months and are prone to excessive ice accumulation.
In addition, the City and County of Denver is looking at implementing Green Infrastructure in this location as a part of its City-wide strategy for improving stormwater quality.
The Exposition and Fillmore Storm Drain will reduce localized flooding problems in the Bonnie Brae neighborhood. Denver’s 2014 Storm Drainage Master Plan identified the need for a storm drain at this location due to the significant amount of storm water that flows on neighborhood streets before entering the existing storm system in Exposition Avenue.
Construction competion is scheduled for April 30, 2020.
The Jackson Street Storm Drain Project provides a critical link between the lower and upper Montclair Basin system for managing stormwater and offers improved flood protection for residents and businesses in the project area between Colfax and 12th Avenues, from Jackson to Albion Streets.
Denver’s Department of Transportation and Infrastructure (DOTI) is designing an improved and expanded storm drain system that will be constructed from Colfax Avenue and Jackson Street near National Jewish Hospital, and eventually tie into the existing storm drain system at 12th Avenue and Hale Parkway on the east side of Colorado Boulevard. This section of expanded stormwater pipes is essential in providing improved flood protection to the project area.
Denver’s Department of Transportation and Infrastructure (DOTI) and Denver Parks & Recreation are improving water quality and constructing a new playground at La Lomita Park, formerly known as Asbury and Tejon Park. This project will remove an existing concrete channel and rebuild the park with a naturalized, vegetated water quality channel that will include play features and educational components for nearby schools. In addition, the recreation lawn and playground is being rebuilt to be more functional for residents and community members.
Construction began in Summer 2019 and is expected to conclude in Summer 2020. The park will be closed to visitors during construction to ensure safety for all.
The City and County of Denver, with Urban Drainage and Flood Control District (UDFCD) and Jefferson County, are making improvements to Marston Lake North Drainageway between South Garrison Street and Stanford Avenue and Balsam Park.
The project, located within Jefferson County and the City and County of Denver, will improve water quality and infrastructure at Stanford and Balsam Park, and develop a sustainable urban design that will result in structures being removed from the regulatory 100-year floodplain designation.
The Sanderson Gulch stormwater project improved the drainage system between Lipan Street and the South Platte River. Construction of the new, higher-capacity drainage system consists of underground, large-capacity stormwater box culverts (large pipes) to manage high-water flows during large storm events. The culvert system has been combined with a naturalized, open-channel on the surface (between the railroad tracks and Platte River Drive) designed to convey and filter base flows and runoff from smaller storms and improve drainageway habitat.
Construction began in February 2018 and was completed in December 2019.
Denver’s Storm Drainage Master Plan identifies the need for storm drain improvements on S. Adams Way between S. Monroe Street and E. Eastman Avenue as part of a larger effort by Denver to bring torm drain infrastructure into compliance with the current drainage criteria.
The storm drain system at this location may be undersized and/or too degraded to completely capture minor storm flows. The S. Adams Way Storm Drain Project will create a design for a storm drain system that, once constructed, will replace and upgrade the existing, inadequate system by shifting and improving a number of inlets and potentially increasing pipe size to meet the drainage criteria for the immediate area.
This phase of the project is to design the storm drainage system only. Funding for construction has not been identified at this time. However, once construction occurs, it is anticipated that the storm drain system replacement and relocated inlets will all take place in existing City Right of Way.
The new storm drain system will go up S. Adams Way between S. Monroe Street and E. Eastman Avenue.
The City and County of Denver and the Urban Drainage and Flood Control District (UDFCD) are conducting an Outfall System Plan Study of stormwater management in the Montclair watershed. The Montclair drainage basin is over 9 square miles and is divided into the lower portion downstream of Ferril Lake in City Park, and the upper portion upstream of City Park. The current stormwater drainage system needs to be improved in some key areas. The Montclair Basin has been identified as a priority basin for storm drainage improvements and water quality improvement.
The Mar Lee residential neighborhood was constructed primarily in the mid to late 1950s. Consistent with development at that time, there are no underground stormwater pipes in this project area. Therefore, stormwater runoff is currently served only with curbs, gutters and roadway cross-pans. Multiple stormwater studies have indicated the potential for excessive stormwater in the streets as well as flooding during heavy storms.
The City and County of Denver and AECOM will proactively coordinate with residents and stakeholders to design a storm drain system that, once constructed, will improve greater protection from flooding with as little disruption to the community as possible. Design of the system will take place in 2019-2020. Funding for construction is expected to be in place within the next five years.
Localized, individual outreach as well as public meetings will be held as appropriate to identify community issues related to storm drainage design and impact.
The Project Team is evaluating the design of a system of stormwater pipes that would run from Sheridan Boulevard eastward down W. Oregon Place and south on S. Xavier Street to Sanderson Gulch, and a second system starting at the intersection of W. Mexico Avenue and S. Wolcott Court, heading east on W. Mexico Avenue to S. Vrain Street and then connecting into Sanderson Gulch.
This project will help improve safety and reduce flood risks to people and property in the Valverde and Athmar Park neighborhoods, two areas of town known to flood. Beginning in mid-February, weather permitting, the city will install a larger stormwater pipe along West Alameda Avenue from Bryant to Decatur Streets, which will provide more capacity to carry and drain stormwater in this area. In addition, lateral storm pipes will be installed along residential streets between West Alameda Avenue and West Dakota Avenue.
The City and County of Denver is working to improve and rehabilitate storm and sanitary (wastewater) mainlines citywide. Wastewater mainlines are usually located in streets or alleys. Some of these systems are more than 100 years old.
Projects are ongoing in neighborhoods for targeted improvements and preventive and critical work.
Weir Gulch crosses under the intersection of S. Utica St. and W. Bayaud Ave. in two 6’x12’ reinforced concrete boxes. There are inlets located at each corner of the intersection that often are covered in debris.
Residents have reported that storm runoff pools at the intersection and heads towards the northwest corner of the intersection rather than draining into the inlets to Weir Gulch as intended. This project will add and upsize inlets and regrade the intersection to direct the flow to Weir Gulch. Concrete flatwork, such as curb, gutter, sidewalk and curb ramps and asphalt street paving will be part of the project.
