Chip Seal Preservation, Northwest and Southwest Maricopa County
Project #: MH2601
Project Description
The Maricopa County Department of Transportation (MCDOT) will be returning to the selec roadways to perform pavement preservation work as part of our ongoing commitment to keep roadways well-maintained. Chip seal work was performed last fall, and crews will be working at locations on the roadways where additional work is needed to meet MCDOT standards. Construction will take place beginning Tuesday, April 21 through mid-May, 2026.
Crews will perform the pavement preservation work along:
- A three-mile stretch of Castle Hot Springs Road, starting at the U.S. Route 60 intersection in Morristown;
- A two-and-a-half-mile stretch of Constellation Road from near 299th Avenue to the county line with Yavapai County in Wickenburg;
- Olive Avenue between 203rd Avenue and Perryville Road;
- Glendale Avenue between Perryville Road and Cotton Lane;
- McDowell Road between 191st and 194th avenues;
- McDowell Road between Perryville and Citrus roads;
- Lower Buckeye Road between 6th Street and 124th Avenue;
- 91st Avenue between Northern and Orangewood avenues;
- McDowell Road between 83rd and 95th avenues.
The project map will be updated to reflect current construction activity as work progresses
The project includes:
- Chip sealing the existing roadway.
- Striping work and pavement markings.
- Cleaning up the work zone and other miscellaneous work.
Drivers should plan for temporary daytime lane closures and possible delays in both directions. During construction, flagging operations will be in place to help direct traffic while work is underway. MCDOT appreciates your cooperation as we complete these improvements. It is recommended to allow extra time for travel in the area. Please watch for work crews, reduce speeds and obey all traffic control signs in the work zone.
