Arizona Department of Transportation issued the following announcement on Feb. 28.
Drivers who use Interstate 10 in the West Valley at night or on weekends should expect restrictions and consider using alternate routes while pavement improvement work is taking place over the next several months, according to the Arizona Department of Transportation.
- I-10 will be narrowed to two lanes in either direction in areas between 75th Avenue and Avondale Boulevard from 9 p.m. to 5 a.m. on weeknights starting Tuesday evening, March 1.
- Westbound I-10 will be closed between 75th Avenue and Loop 101 (Agua Fria Freeway) from 9 p.m. Friday to 5 a.m. Monday (March 7). The northbound Loop 202 (South Mountain Freeway) ramp to westbound I-10 will be closed. The westbound I-10 on-ramp at 67th Avenue also will be closed.
As part of a $12 million project to improve I-10’s riding surface in areas between I-17 and Avondale Boulevard, crews have been working since last fall to remove sections of worn asphalt.
Crews will now focus on smoothing the freeway’s concrete pavement with a process called diamond grinding. Specialized machines with rotating drums containing diamond-tipped blades are used to remove a thin layer of the freeway’s existing pavement while also adding small grooves to the surface.
The diamond grinding process has been used on several other sections of Valley freeways, including Loop 101 (Price Freeway) between US 60 and Loop 202 (Santan Freeway) in the southeast Valley; Loop 101 (Pima Freeway) between I-17 and Pima Road in the north Valley; and Loop 202 (Santan Freeway) between I-10 and Loop 101 in the Chandler area.
