Beginning Friday, September 4, Exposition Avenue from Broadway to Lincoln will be reduced to a single lane for eastbound travel only until the end of October. Message boards are in place to alert drivers about the closure and encourage them to use alternate routes. In addition, work will require sidewalk closures and detours will also be in place for pedestrians. On-street parking and access to parking lots along this stretch of Exposition Avenue will also be limited during this time.

South Broadway & I-25 Improvement Projects

The City and County of Denver's is redesigning the interchange of I-25 and Broadway. The improvements aim to create a safe and efficient area for all transportation modes ̶ pedestrian, bicycle, transit, and automobile.

The redesign of the ramps to I-25 is intended to help ease congestion on Broadway and Lincoln, reduce the potential for crashes, enhance bicycle and pedestrian connectivity in the area, and improve access to and from RTD’s Broadway Station.

The improvements will also help accommodate economic development of the Gates District and Broadway Park redevelopment. This project will expand on previous improvements that have been implemented by Denver and CDOT.


Project Features:

  • Improves access to RTD’s Broadway Station by constructing a new north entrance through Exposition, allowing riders and transit buses to bypass the interchange area.
  • Increases the pedestrian and bicycle access to transit station by building new shared-use paths and rebuilding existing sidewalks.
  • Improves pedestrian and bicycle safety by building new, well-lit facilities with adequate protected space along and across Broadway and Exposition
  • Moves vehicles more efficiently with coordinated traffic signals and new lane configurations on Broadway, Ohio, and Lincoln.
  • New configuration of the southbound I-25 on-ramp minimizes backups on Broadway between Exposition Avenue and Kentucky Avenue

DOTI is committed to keeping people moving during construction. Crews will do as much work as possible to minimize effects. At the same time, there will be traffic shifts, lane reductions and detours during construction. DOTI will announce these changes as they are scheduled.

Construction Update - week of October 26, 2020:

During the week of October 18, crews continued concrete paving the north side of the roadway on Exposition and replacing sidewalks and driveways. Other work included final asphalt removals, formwork for more concrete paving in front of Gold Star Radiator, and additional curb and gutter work. 

This week, crews will be finishing up concrete paving on the north side of Exposition and replacing the driveway on the northeast corner of Exposition and Broadway. Other work planned is continued drainage line installation, curb and gutter work site wide, and preparing for a traffic shift to westbound on Exposition between Broadway and Lincoln. 

Please note that all construction schedules are weather dependent and subject to change. 

Starting on Monday, September 14, the left lane on Lincoln between Ohio and Exposition will be closed to all through traffic. The closure is in place because E Exposition is presently under a single lane configuration for eastbound traffic only with no left (westbound) turns permitted onto Exposition from Lincoln. This closure will be in effect until approximately October 31. 

No other lane or configuration changes will take place on northbound Lincoln between Ohio and Center. Previously scheduled striping has been cancelled. 

Please call the project hotline at 303-960-2825 if you have additional questions.

Current Phases

Phase I:

Phase I reconstructs Exposition Avenue from Lincoln to Bannock Street. This construction phase expands Exposition west of Broadway to future align with the Bannock Street extension and installs new traffic signals on Exposition at Broadway and Lincoln.

This phase also minimally widens and reconstructs Broadway for half a block south of Exposition to provide wider sidewalks and streetscape.

Meetings and Public Outreach Materials:

Project Updates and Schedule:

The construction of Phase I will begin in August 2020.  The duration of this phase is appx. one year.

Phase II:

Phase II replaces the southbound on-ramp to I-25 from Broadway and finalizes the extension of Bannock Street. This phase focuses on the multimodal connection improvements on Broadway, Lincoln, Ohio, and Kentucky. This phase also includes the reconstruction and installation of new traffic signals on Ohio Avenue between Lincoln and Broadway into RTD’s Broadway Station.

Project Updates and Schedule:

The design of Phase 2 is underway, and will take about a year to complete.  Construction likely won’t begin until Q1 2022.

Prior Efforts

South Broadway Reconstruction Project Wraps Up

Denver's Department of Transportation and Infrastructure has reconstructed a stretch of South Broadway from Kentucky to Arizona and a section of Mississippi Avenue between the Consolidated Main Line (CML) Railway and Sherman Street. The project began in March 2016 with the goal of improving overall mobility for people on bikes, on foot and in vehicles. 

Schedule, maps, updates »

Right of Way:

The City and County of Denver's Broadway Arizona to Exposition Project will be constructed in three to four phases. As each phase is funded for construction, the City and County of Denver (City) will follow the Federal Highway Administration (FHWA) guidelines for acquisition of required properties within the project corridor. This guidance provides the City will follow their standard process of completing Right-of-Way plans, then City Council passing an ordinance authorizing property negotiations and acquisitions. Upon ordinance passage the City will contact affected property owners and begin the negotiation discussions, offers will be made after appraisals or value finds are completed. The City reserves the right to utilize imminent domain but will continue to negotiate to meet fair value agreements through the acquisition process.

Impacts determined during the Environmental Assessment can be found on page 3-20 and 3-21 of this document:

Final Design Project Scope:

The overall project scope for these two projects will reconstruct South Broadway from Kentucky Avenue to Arizona Avenue and Mississippi Avenue between the Consolidated Main Line Railway (CML) and Lincoln Street. Improvements will include roadway widening; multi-use paths from Arizona to Kentucky along Broadway and from the CML to Sherman along Mississippi; pedestrian and street lighting; landscape and streetscape; and upgraded signalized intersections at Broadway/Tennessee and Broadway/Mississippi.

Adopted in April 2016, the I-25 and Broadway Station Area Plan guides the future growth around the station and surrounding neighborhoods. The Plan identified the I-25 Interchange and Broadway Reconstruction as a project that will enhance the multi-modal environment within the S. Broadway corridor.
