PHOENIX – A project to improve the road surface along Interstate 10 in areas west of the I-17 “Stack” interchange in the West Valley is scheduled to begin this weekend (September 10-13 ), according to the Arizona Department of Transportation.
Crews will remove the top layer of worn and worn rubberized asphalt along sections of I-10 during a series of weekend closures this fall.
The $ 12 million project will begin with the closure of the I-10 eastbound freeway between Avondale Boulevard and 99th Avenue from 9 p.m. Friday to 5 a.m. Monday (September 13). Eastbound I-10 ramps on Litchfield and Dysart roads will also be closed. Drivers should consider exiting before closing and using alternate routes. Traffic exiting Avondale Boulevard will head south and take Van Buren Street eastbound.
Improvements to I-10 this fall will take place in the segments between I-17 and Avondale Boulevard with the exception of the area between 43rd and 67th avenues. This part of I-10 received a new layer of rubberized asphalt during construction of the Loop 202 (South Mountain Freeway) interchange, which opened to traffic in late 2019.
The project will also adjust the lane interlacing to allow the capacity of the south ramp of Loop 101 to I-10 westbound freeway to be increased from one to two lanes. The development of the lanes and shoulders will also allow the addition of another I-10 westbound traffic lane in the area between 67th Avenue and Avondale Boulevard.
After the asphalt removal work this fall, crews will follow up from early 2022 to smooth the concrete pavement along I-10 by diamond grinding the surface. The diamond grinding process uses specialized machines with rotating drums containing diamond tipped blades to remove a thin layer of concrete pavement from a highway while adding small grooves to the surface.
ADOT has also used diamond grinding on sections of Loop 101 and Loop 202 in the Phoenix area.
