To prepare for upcoming work, crews will CLOSE Maricopa/Casa Grande Highway just east of Napa Auto Parts, scheduled for the night of Tuesday, April 3, beginning at 9 p.m. until approximately 5 a.m. Wednesday, April 4.

In addition, crews will also CLOSE Honeycutt Road, east of SR 347, scheduled for the night of Thursday, April 5, beginning at 9 p.m. until approximately 5 a.m. Friday, April 6.

Detour signage will be in place to direct travelers around the closures. These closures will allow crews to set concrete barriers and remove and replace striping, so that on the following morning, the roads will be open for travel with traffic shifted away from the upcoming work activity.

Head to for an overview of the project, frequent updates on traffic impacts, project timelines, maps and videos of what the project will look like when complete. The City of Maricopa has also established a 24/7 Hotline for you to call and get answers to more specific questions or concerns at 520-316-6910.

The SR 347 Overpass will create a bridge over the Union Pacific Railroad (UPRR.) Traffic on SR 347 averages more than 31,000 vehicles per day and future (2040) projections show over 60,000 vehicles per day. There are currently 40 to 60 trains per day; the UPRR has plans to expand service, which would increase train traffic upwards of 100 trains per day. Additionally, the Amtrak station is located just west of the intersection and vehicular traffic is routinely delayed for its passenger operations. The completion of the Overpass project will drastically ease traffic congestion and increase safety in the area.
