Closures and Detours related to Big Shift Construction

Road Closures

As Big Shift construction crews dig trenches in order to lay new hot water pipes, there will be road closures and detours for vehicles, bikes and pedestrians. Stay up to date with the latest closures and detours below.

California Avenue

Beginning Dec. 1, 2025 and continuing into 2026, a portion of California Avenue near Cruess Hall will be closed to vehicular and bicycle through traffic. The closure extends from the intersection at North Quad to the intersection at Tennis Court Lane, near the campus gate. 

Bike Detours

Bicycles, scooters and other micromobility vehicles, will be directed around the California Avenue closure via Regan Hall Circle and Sprocket Bikeway.

Pedestrian Detours

Pedestrians will still be able to walk down California Avenue, but the west sidewalk near Cruess Hall will be closed. Pedestrians will be directed to the eastern sidewalk via crosswalks at the North Quad intersection and near Cowell Building.

Vehicular Detours

The closure will only affect vehicles authorized to drive through campus, including delivery vehicles. This traffic will be directed to other campus entrances, including the entrance on First Street near the A Street intersection and the entrance on Hutchison Drive near the intersection of Kleiber Hall Drive.
