District-wide Pavement Preservation Projects - Southwest District

The Arizona Department of Transportation has allocated $36 million for multiple pavement preservation projects on highways across the state during fiscal year 2022, which began July 1, 2021, and ends on June 30, 2022. 

ADOT evaluated existing pavement conditions to identify locations in each of its seven districts that are currently in good condition. The goal is to undertake preventative-maintenance projects in those locations now so roadways remain in good condition vs. undertaking much more costly and impactful repair projects later - after the pavement has deteriorated. Investing in preventative-maintenance projects directly aligns with ADOT’s Long Range Transportation Plan goal of maintaining, preserving and extending the service life of existing state transportation system infrastructure. 

During fiscal year 2021, Southwest District was able to treat 1,056 lane-miles by sealing cracks, flushing with oil or applying a micro-seal.  The pavement preservation work is cyclical as it moves around the state to treat good pavements to keep them in good condition. 

During fiscal year 2022, work has rotated and Southwest District has just over 150 lane-miles scheduled for crack filling.

Expect to see crews at work in different parts of the state during different times of the year based on outside air temperatures and other weather conditions. Two pavement preservation projects are scheduled for fiscal year 2022.

  • US 95 between mileposts 54 and 63.5 is scheduled to begin in October 2021
  • Interstate 8 between mileposts 115 and 134.6 is scheduled to begin in November 2021.

ADOT will provide more specific information about project schedules and potential impacts as it becomes available.

Projects are selected from across the state on a priority basis; the number of lane-miles within a district is not consistent year to year.  This variation within a district is normal.  Each year, cost savings on projects and delays due to weather may result in extra projects added during May and June.

ADOT crews will continue to routinely check all mileposts along every route to fill potholes as needed.  

What to expect:

The estimated construction dates will be updated as schedules are confirmed.

  • Lane restrictions or closures that impact travel could occur.
  • Drivers should expect lane and ramp restrictions or closures and plan for possible delays.
  • Drivers should slow down and use caution around construction personnel and equipment.
