Grant Road Improvement Project Phase II Stone to Park - Grant Road and Sixth Avenue Intersection Work

On Tuesday, April 18, 2017 and Wednesday, April 19, 2017, from 9 a.m. to 1 p.m. each day, Markham Contracting, under contract with the City of Tucson Department of Transportation, will install temporary traffic signal wires and remove existing traffic signal poles at the Grant Road and Sixth Avenue intersection. The work will take place in the eastbound and westbound Grant Road left turn lanes at the intersection. During the work, the traveling public can expect the following:

  • Eastbound and westbound left turn lanes will be temporarily closed at the intersection
  • No left turns will be permitted from Grant Road to Sixth Avenue
  • All right turn movements will be permitted

Work to widen Grant Road from Stone Avenue to Park Avenue began in March. The contractor is currently removing and salvaging landscape material, excavating, relocating/installing utilities, and completing investigative potholing on the south side of Grant Road. Utility companies continue to work to relocate infrastructure, which could lead to periodic travel lane restrictions along this section of Grant Road.

Crews will work Monday through Thursday, from 5:30 a.m. to 4 p.m. each day, with occasional night work and weekend work. The project is scheduled to be complete in summer 2018.

The improvements include six vehicular travel lanes, protected bike/pedestrian street crossings, drainage improvements, indirect left turns at Stone Avenue and First Avenue, bike lanes and sidewalks, bus pullouts and bus shelters, and public art. For more information, please visit or email

The project is part of the $2.1 billion Regional Transportation Authority (RTA) Plan, which will be implemented through 2026. The multimodal plan, nearly halfway through implementation, includes roadway, safety, transit, environmental and economic vitality improvements. This project is managed by the City of Tucson.
