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. 

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

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.

Upcoming Work

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.

Once curb extensions are completed, crews will begin asphalt removal and replacement on 19th Avenue from Broadway to Park Avenue.

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.

Construction Updates — January 2018

Traffic impacts are expected Monday, January 15 through Friday, January 19 at the following locations:

  • Sherman Street: both lanes closed south of 19th Avenue, with detours in place and on-street parking restricted
  • 19th & Grant: southwest corner closed to pedestrians
  • 19th Avenue: right lane closed 24/7, middle lane closed 8:30 a.m to 3:30 p.m; one lane open at all times

Transit Impacts

  • For routes on 19th Avenue, RTD buses will drop off and pick up passengers at stops before or after the construction zone. 

Expect to see construction activity at each intersection along 19th and 20th. Crews will need to remove the existing concrete curb ramps, install new storm water inlets, replace some of the storm water pipes under the concrete and rebuild the ADA (American with Disabilities Act) concrete ramps at the corners. Several of the intersections will also receive new traffic signals designed for a two-way traffic operation.

Working hours will be Monday through Friday, 7 a.m. to 5 p.m. Work may occur occasionally on the weekends. Business and resident access will be maintained during construction. Detour signs will be posted. The public’s patience and cooperation is greatly appreciated. All work is weather dependent and subject to change.
