Current Transportation & Infrastructure Projects

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 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.

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.

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.

Updates and details about the 33rd Street Outfall project

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.

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.

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.
