November 2026
Construction continued this fall on Phase II of the State Route 60/Potrero Boulevard Interchange Project. See the latest improvements taking shape across the project area in September’s Potrero in Progress video below.
Truck Detours
Beginning the week of Monday, November 9, 2026, the westbound SR-60 Western Knolls Avenue on- and off-ramps will be temporarily closed to trucks, freight vehicles, and tractor-trailers as crews work to realign Western Knolls Avenue. The ramps will remain open to passenger vehicles.
During the closure, trucks and freight vehicles will be detoured to Potrero Boulevard and Oak Valley Parkway to access I-10 and reconnect to westbound SR-60. The closure will remain in place 24 hours a day, seven days a week, and is anticipated to continue through spring 2027.
Construction activity will take place on weekdays and include roadway repaving, lane striping, and utility relocation.
