Maricopa Casa Grande Highway to close overnight for delivery, placement of large support beams for new State Route 347 overpass

Drivers should allow extra travel time and consider alternate routes

The Arizona Department of Transportation advises drivers who use Maricopa Casa Grande Highway (MCGH) to plan for overnight road closures this weekend while construction continues on the State Route 347 overpass project.

ADOT advises drivers to slow down and use caution while the following restrictions are in place:

  • MCGH will be closed in both directions from SR 347 to Pershing Street from 9 p.m. Friday, Jan. 11, to 6 a.m. Saturday, Jan. 12, and from 9 p.m. Saturday, Jan. 12, to 6 a.m. Sunday, Jan. 13.
  • MCGH-to-SR 347 Detour: Motorists driving northeast on MCGH can use Maricopa Groves Parkway to access north- and southbound SR 347.
  • SR 347-to-MCGH Detour: Motorists driving southbound on SR 347 can travel east on Edison Road and follow the detour signs to access MCGH.
  • Flaggers will direct traffic and limit access to local traffic only.
  • SR 347 will remain open while the overnight closures on MCGH are in effect.

The full closure of MCGH is needed for the delivery and placement of large concrete support beams, called girders, onto the overpass structure currently under construction at SR 347.

The 82-foot-long girders will be delivered on special 18-wheel flatbed trailers and then erected into place using cranes. The placement of the girders represents a major milestone of the project.

The future above-grade structure will resolve traffic congestion created at the existing street-level intersection of SR 347 with the Union Pacific Railroad track. Learn more on the project web page.

Also: Maricopa officials have notified ADOT the city is planning to close MCGH briefly sometime between 10:30 a.m. and 1 p.m. Thursday, Jan. 10. The full closure of MCGH, which is scheduled to last less than 30 minutes, is needed to relocate the city’s iconic California Zephyr railcar to a new location.

The city will close MCGH between SR 347 and the Maricopa Unified School District Office, so trailers transporting the California Zephyr and the cranes that will be used to move the railcar into place can safely pull onto the highway. Maricopa Police will provide an escort while the California Zephyr and cranes are being transported to the new location.
