Drivers should expect delays and allow extra travel time

The Arizona Department of Transportation advises drivers to plan for lane restrictions and temporary driveway closures along State Route 83 between Black Oak Drive (milepost 31) and Lower Elgin Road (milepost 29) beginning at 7 a.m. Monday, Jan. 19,  and ending Friday, Jan. 30, as a pavement rehabilitation project continues in Sonoita. 

Motorists can expect the following restrictions:

  • Daily lane restrictions on east- and westbound SR 83 between mileposts 31 and 29 from 7 a.m. to 5 p.m. Monday through Friday 
  • Rolling lane restrictions as crews work through multiple sections of the project area each day. Note: Crews are tentatively scheduled to partially close driveways on SR 83 for approximately 15 minutes to allow placement, compacting and curing of asphalt. 
  • Flagging operation in the project area.
  • Speed limit of 25 mph in the work zone

Drivers should allow extra travel time, use caution, be prepared to slow down and merge safely when approaching and traveling through all work zones.

Schedules are subject to change due to weather and other unforeseen circumstances.
