A project to improve the pavement surface along State Route 51 between the Interstate 10 “Mini-Stack” interchange and Shea Boulevard in Phoenix began the weekend of March 13-16, and is expected to take approximately six months to complete.
The pavement rehabilitation project by the Arizona Department of Transportation, in coordination with the Maricopa Association of Governments, will run along a 9.5-mile section of State Route 51, between Interstate 10 (Papago Freeway) and Shea Boulevard. The purpose is to extend the life of the pavement and improve the driving experience and safety.
The SR 51, I-10 to Shea Boulevard Pavement Rehabilitation project is included in the Regional Transportation Plan for Maricopa County and funded through Proposition 479, a countywide dedicated half-cent sales tax for transportation improvements approved by voters in 2024.
This work began with a series of weekend closures along SR 51 so crews can remove the top layer of older, worn asphalt pavement along the nearly 10-mile stretch. They also will use the concrete pavement treatment known as diamond grinding to provide a smoother ride. The process adds small grooves to the pavement to help limit tire noise.
The $17.8 million project is scheduled for completion this fall. In addition to weekend closures, the work will require weeknight lane and ramp restrictions or closures.
