20th Street Improvement Project

Project Overview

The Phoenix Street Transportation Department is planning to implement a series of improvements along 20th Street between Glendale Avenue and the Grand Canal south of Osborn Road.

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

In 2016, city staff applied for and were awarded a Maricopa Association of Governments (MAG) Design Assistance Grant. The grant will fund an assessment report of the current conditions and develop a series of safety improvements for the 20th Street bicycle corridor. 

20th Street has two to four travel lanes in the corridor and can provide a s​afe, easy, rideable and walkable thoroughfare to connect residents to schools, employment, restaurants and shopping (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.

October 2022 Project Update​​​​​​​​​​​​​​​​​​​​​​​ ​​

A virtual public meeting was hosted on October 19, 2022 at 6 p.m. via Webex to provide the community with an update about Phase 1A of the project. A video recording of the meeting is available below and on YouTube​. ​​​

Phase 1A

This improvement project includes implementing buffered bicycle lanes, narrowing travel lanes, Americans with Disabilities Act (ADA) ramp upgrades, ADA compliant driveway upgrades, street lighting and traffic signal upgrades at the Osborn Road, Indian School Road, Campbell Avenue and Highland Avenue intersections.​​


  • Design anticipated to be complete summer 2024
  • Construction anticipated to begin summer 2025 (pending right of way acquisition)

Phases 1B and 2

Phase 1B includes the 20th Street segment from Highland Avenue to Missouri Avenue and recommends bike lanes, buffered bike lanes, protected bike lanes and a shared use path where appropriate. Phase 2 includes the 20th Street segment from Missouri Avenue to Glendale Avenue, and then Glendale Avenue from 20th Street to Ocotillo Road. Shared Lane Markings (“sharrows") are recommended on this segment, which will assist users in reaching the Piestewa Peak Trail network.
