Grant Road Improvement Project

City of Tucson's Grant Road Improvement Project


In advance of roadway construction on Phase 3 & 4, there are several activities continuing to take place as part of the project. New Tucson Electric Power poles and lines have been installed and telecommunication fiber from the old power poles are currently being relocated to the new poles. The remaining utility work is anticipated to take 4 to 5 months to complete. Following this work, Tucson Electric Power will remove the old poles from the project site and the Department of Transportation and Mobility will proceed with advertising the project for construction bid.

The Regional Transportation Authority’s (RTA) board approved the Intergovernmental Agreement (IGA) to provide funding for the upcoming construction phase. The IGA will be presented to the Tucson Mayor and Council on January 11, 2023.

Roadway construction is anticipated to begin in 2024.

The Regional Transportation Authority, a political subdivision of the state and independently governed, has invested more than $1.4 billion in transportation projects and services to improve mobility, safety, economic vitality and quality of life in the region. The RTA collects a half-cent excise (sales) tax from its special taxing district within Pima County to fund its 20-year regional transportation plan. The plan and tax were approved by voters in May 2006. The Grant Road Improvement project is part of the RTA plan and is managed by City of Tucson, Department of Transportation and Mobility.
