I-40 Paving Projects: AZ-CA Stateline to SR 95

I-40 Paving Projects: AZ-CA Stateline to SR 95





The Arizona Department of Transportation has initiated two construction projects to replace the top-riding surface along 8 miles of Interstate 40 between the Arizona-California state line and the junction with State Route 95 (mileposts 0 to 8). 

The first project - between mileposts 2-8 - begins two miles east of the Arizona-California state line and ends at the SR 95 junction. Construction is scheduled to begin this summer and be completed in May 2025.

The second paving project - between mileposts 0-2 - will be from the Arizona-California state line to Needle Mountain Road. Construction is scheduled to begin later this summer and be completed in early 2025.


Project Elements

The purpose of these projects is to extend the life of the roadway and improve the riding surface for drivers. The work will include:

  • Remove and replace the existing top layer of pavement on I-40 between the Arizona-California state line and the junction with SR 95 (mileposts 0 - 8).

  • In addition to the mainline, roadway shoulders, ramps and a cross road will receive the new pavement overlay.

  • Remove and replace a bridge deck, bridge approach slabs and bridge barrier.

  • Other related work.


What to expect during construction

Lane restrictions will be limited to overnight hours. No restrictions are anticipated  during daytime hours, weekends or state holidays. Business access will be maintained during construction, although there will be brief restrictions when work crosses in front of businesses.

The restrictions include:

  • Intermittent overnight lane restrictions on east- and westbound I-40 from 6 p.m. to 9 a.m. from Sunday evenings through Friday mornings. 

  • I-40 will be reduced to one lane in each direction during overnight paving work. 

  • There will be times during the project when extended lane restrictions will be required in each direction. ADOT will provide advance notice of the extended lane restrictions.

  • Motorists should plan for extra travel time and be prepared for delays of up to 15 minutes.

  • The speed limit will be reduced in the work zone.

ADOT reminds drivers to proceed through the work zone with caution, slow down and watch for construction personnel and equipment while the restrictions are in place.
