Projects that will possibly slow your ETA - so be watching!


Interstate 10, Twin Peaks Interchange


Beginning Tuesday, Feb. 9 through Thursday, Feb. 11, crews will install a new four-way traffic signal at the intersection of Twin Peaks Road and Coachline Blvd. Installation will require interim lane closures at the intersection. Marana Police Department officers will be on-site to direct traffic at the existing four-way stop. Marana will activate the new signals in early August, prior to the start of the school year.

Construction vehicles are using the left lane along the eastbound Frontage Road from Tiffany Loop to Avra Valley Road as a two-way haul route. During this time, the right lane along eastbound frontage road will remain a one-way, eastbound-only route for all non-construction related vehicles.
