PHOENIX ‒ Crews are scheduled to pour the concrete deck for the final section of a State Route 347 overpass in Maricopa starting this week as the Arizona Department of Transportation moves ever closer to opening the bridge and new highway alignment by early summer.

The work is scheduled for 1 to 5 a.m. Thursday, April 25, and from 8 p.m. Tuesday, April 30, to 5 a.m. Wednesday, May 1. For the safety of drivers, Maricopa-Casa Grande Highway will be closed at the overpass and traffic will be re-routed while crews pour the concrete.

Completing the bridge deck above Maricopa-Casa Grande Highway will clear the way for crews to begin paving the new alignment of SR 347.

Drivers should watch for lane restrictions and possible delays starting in late April as workers begin connecting the new alignment with the current SR 347 at Alterra Parkway on the south and Hathaway Avenue on the north.

A new traffic signal at Plainview and Honeycutt roads will begin operating in late April. Plainview is a new street built just west of the Maricopa Unified School District to connect Maricopa-Casa Grande Highway with Honeycutt Road. Northbound drivers on Maricopa-Casa Grande Highway will use Plainview and Honeycutt Road to reach SR 347’s new alignment.

The new alignment is expected to be ready for traffic by early summer. Honeycutt Road, which has been closed for the past few months to accommodate construction, will open to the new alignment at the same time. An extension of Honeycutt Avenue, located south of the railroad tracks, also will connect with the new alignment.

Once the new alignment is open to traffic, crews will begin making changes to the current roadway, including cul-de-sacs just north and south of the railroad crossing and just north of Alterra Parkway. That work is expected to be completed by November.

The $55 million overpass will eliminate the need for drivers to wait for trains crossing SR 347. Train traffic and vehicular traffic are expected to double in the area in the next 20 years.
