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.
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.
Motorists driving northeast on MCGH can use Maricopa Groves Parkway to access north- and southbound SR 347. 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.
