19th & 20th Avenues Two-Way Conversion


Denver Public Works will convert 19th Avenue and 20th Avenue to provide two-way vehicular travel on both streets through the North Capitol Hill/Uptown area, between approximately Broadway and Park Avenue West. The emergence of multi-family residences, street-level retail, restaurants, offices, and ongoing development in the area has changed the community, and this project will help reflect this change. New bicycle facilities will be included on both 19th and 20th Avenues, and Grant and Logan Streets will also be converted to two-way vehicular operation between 18th and 20th Avenues. 

As more people choose to live in this area and commute to downtown either by transit, foot, or bicycle, there is an increased need to better integrate multi-modal travel into the corridor. This conversion will allow for more "complete streets" and will contribute to the urban neighborhood character that has emerged. 

Construction Updates — May 2018

19th Avenue and 20th Avenue are open in the final 2-way traffic configuration.
Logan Street is open to 2-way traffic between 18th and 20th Avenues.

There may be various lane closures on both 19th and 20th Avenues as crews complete signing and striping. Flaggers will be present to stop and direct traffic through the work zone if necessary.

Parking is now permitted on both 19th and 20th Avenues.

Project Goals

  • Improve connectivity by linking and easing access to existing routes
  • Increase safety with improved bicycle and pedestrian facilities
  • Provide traffic calming in an increasingly residential area 
  • Enhance neighborhood character with consistent street patterns

Related improvements: Crews are rebuilding ADA concrete curb ramps, installing new storm water inlets and replacing storm water infrastructure currently under the concrete. Several intersections will also receive new traffic signals designed for two-way traffic operation.

Project Updates

As of the end of December 2017 the project progress is 60% completed.  Project completion and updates include:

  • 350 cubic yards of concrete have been poured, the equivalent of one-tenth of an Olympic-size swimming pool.
  • New stop signs have been placed on the intersection of 19th Avenue and Sherman Street, and 19th Avenue and Grant Street to help control oncoming traffic equally.
  • Intersection work on 19th Avenue and Lincoln Street.
  • Concrete work and removal of traffic signals on 20th Avenue.
  • Curb extensions on Grant Street and 19th Avenue.

Upcoming Work

Crews will be working along 19th Avenue to address the protection of bike lanes and parking.

  • From Broadway to Grant Street, crews are going to extend 14 concrete curbs. The extended curbs will help create protected bike lanes and parking on 19th Avenue. The work will last until mid-February.
  • Asphalt mill and overlay on 19th Avenue from Broadway to Park Avenue. This phase is expected to start in April.
  • Road and bike lane striping work will start end of April. 
  • Utility relocation crews will continue to work in various locations on 19th Avenue, they will be relocating the aerial utilities to underground.

Street Light Work on 20th Avenue

Xcel Energy is in the process of replacing the street lights that were removed along 20th Avenue. The work is expected to end the first part of February.

Construction is expected to last until May.

Motorists, please be aware that traffic delays are scheduled to occur Monday through Friday from 8:30 a.m. to 3:30 p.m.

Normal working hours are Monday-Friday, from 7 a.m. to 5 p.m. No weekend work is expected.

Street parking near active construction zones will be removed 24 hours a day while crews are occupying the work area. The parking meters will be bagged and parking will not be allowed.

Sections of the sidewalks in the construction zone will be closed mostly near the street corners. Signed detours will be in place to guide pedestrians around the closed areas. Access to businesses and residences will be maintained.
