*UPDATED START DATE*

MARANA - The Town of Marana continues construction work to improve a two-mile section of Twin Peaks Road through Rattlesnake Pass.

The upcoming phase of construction will require a full closure of Twin Peaks Road between White Stallion Ranch Road and Silverbell Road to the north side of the Twin Peaks Road/Silverbell Road intersection at the Safeway Shopping Center, as well as from that intersection north on Silverbell Road to Sunflower Park Drive. The closure is scheduled to occur from Thursday, May 22, at 10:00 p.m., through Sunday, August 3, 2025.

Full closure is necessary to ensure public safety and to accelerate construction, which will shorten the schedule by approximately two months.

Access to all area homes and businesses in the closure area will be maintained throughout the closure. Suggested detours include using Saguaro Peaks Boulevard, West Lambert Lane and Silverbell Road.

The work is part of the Twin Peaks Road Widening project at Rattlesnake Pass by Hunter Contracting to construct an additional travel lane in each direction between Silverbell Road and Quarry Road (Cement Plant Road). The project began in July 2024 and is scheduled to be completed in August 2026.

Project improvements include:

  • Widening the existing two-lane roadway to add an additional travel lane in each direction with a median between the eastbound and westbound lanes
  • Installing new traffic signals at the intersection of Twin Peaks and Saguaro Peaks roads, and at the Twin Peaks-Silverbell intersection
  • Improving drainage in the project area, including storm drain structures and stormwater catch basins
  • Constructing a new slope containment wall with architectural treatment through the pass
  • Constructing curbs and sidewalks, with ADA-compliant ramps
  • ·Constructing a multi use path from White Stallion Ranch Road to Old Silverbell Road
  • Irrigation and landscaping
  • Underground utility improvements and relocations 

Regular updates will be provided on the Town of Marana traffic alerts page.
