20th Street Improvement Project

Project Overview

As part of an effort to make the city's roadways safer for people that drive cars, ride bicycles and pedestrians, while maintaining the existing number of travel lanes and improving connections with transit, the city of Phoenix Street Transportation Department is proposing a series of transportation improvements for 20th Street between Glendale Avenue and the Grand Canal south of Osborn Road.

The 20th Street project corridor was identified as priority #4 out of 39 corridors for implementation in the City of Phoenix Bicycle Master Plan adopted by City Council in November 2014. 

In 2016, City staff applied for and was awarded a Maricopa Association of Governments Design Assistance Grant to complete a project assessment report to assess the current conditions and develop a series of safety improvements for the 20th Street bicycle corridor to transform it to a low-stress environment for bicyclists. 

20th Street has two to four travel lanes in the corridor, and can provide a safe, easy, rideable and walkable thoroughfare to connect residents to schools, employment, restaurants and shopping (i.e. Town and Country Shopping Center, Camelback Colonnade Center) and major bus routes.  The proposed project will greatly enhance connectivity with existing and planned bicycle and pedestrian infrastructure and transit service for this transportation corridor.   

The proposed plan for this project maintains the existing number of travel lanes on 20th Street; enhances pedestrian safety; and includes various bicycle lane designs such as buffered bike lanes. 

  • Bike Lanes

    • Protected bike lanes

    • Buffered bike lanes

  • Pedestrian Safety Improvements

  • Shared-Use Pathway

  • Intersection Improvements


Project Location

The 20th Street corridor is located approximately a quarter mile east of SR-51, and provides access to four grade separated non-motorized passes of the freeway at the Grand Canal, Campbell Avenue, Maryland Avenue, and the Arizona Canal. 

This corridor is the 4th highest priority of the City of Phoenix Bicycle Master Plan, connecting the regional shared-use path along the Grand Canal to the access road.

Project Updates


Oct. 9, 2019

20th Street is scheduled to be paved in late October and will be ready for traffic lane striping improvements. Traffic lane striping on 20th Street between the Grand Canal and Osborn Road will be modified to include bicycle lanes and the existing bike lanes between Osborn and Indian School Roads will be modified to include buffers. The number of vehicle travel lanes and on-street parking will not change. Buffers will be added to other suitable locations to create separation between bicyclists/pedestrians and motor vehicles. This design is intended to create a safer corridor for everyone. Public Notice

June 20, 2019

After undergoing an extensive public outreach effort, the proposed 20th Street Improvements project was presented to the Citizens Transportation Commission and the City Council Aviation and Transportation Subcommittee. The two-phased project links downtown Phoenix with the Camelback East Core.  The two committees were supportive because the project uses existing infrastructure and low traffic volume streets to develop this segment of an active transportation network. The first step in the project implementation will take place this summer. This initial phase will include the repaving of 20th Street from Greenfield Road to Indian School Road. The existing number of traffic lanes will remain as well as on-street parking. However, traffic lanes will be narrowed and buffering areas will be created to help separate and protect bicyclists and pedestrians from cars and create a safer corridor for everyone. The stretch north of Indian School Road will be included in a future capital improvement project for design and construction. 


Public Input Opportunities

Your participation, including providing valuable feedback to the project team as this study progresses, is highly encouraged. Throughout the project process, public meeting(s) will be held. The public meeting(s) will be interactive and will encourage active engagement of meeting participants.  Details about future public meetings for this project will be posted on this webpage.
