Lane closure continues on State Route 77 near Mammoth

The Arizona Department of Transportation advises drivers to plan for the following restrictions on State Route 77 near Mammoth in Pinal County as a four-month pavement-improvement project continues:

  • Southbound SR 77 will be closed between Hollywood Drive and Miguel Road for road improvements from 4 a.m. to 7 p.m. daily through Friday, March 2.
  • Drivers should allow plenty of extra travel time and plan for delays. A pilot car and flaggers will guide traffic through the work zone.
  • Vehicles are restricted to 12 feet in width and  100 feet in length.
  • Watch for intermittent shoulder closures on north- and southbound SR 77 from milepost 113 to milepost 120 through April.

The $4.3 million, 120-day project is north of Mammoth between mileposts 113 and 120. The work includes milling the existing asphalt and replacing it with new asphalt and a double chip seal coat application.

Drivers should proceed through the work zone with caution, slow down and watch for construction personnel and equipment.
