Understanding the Caltrans Weekend Construction Zones

The first major project shuts down westbound Interstate 80 in San Francisco between 5th and 15th Streets. This full weekend closure runs from Friday at 11 p.m. until Monday at 6 a.m. for essential concrete repaving.

Route 37 Upgrades and Regional Impacts

Simultaneously, State Route 37 is undergoing a 55-hour full closure in both directions between Mare Island in Vallejo and Sears Point. This North Bay project runs from Friday at 10 p.m. through Monday at 5 a.m. to prepare for severe weather.

Crews are actively removing the center median and raising vulnerable portions of the roadway by three feet. This crucial elevation work aims to prevent flooding during heavy rainfall and anticipated El Niño conditions.

Transportation officials strongly advise motorists to utilize public transit or alternative corridors like the Richmond-San Rafael bridge. Drivers should also consider checking out local travel tools before heading out.

Motorists are specifically instructed to avoid using the Bay Bridge to enter San Francisco during the construction period. Alternative paths like the San Mateo-Hayward bridge, State Route 121, and Route 29 offer better workarounds.

If your weekend plans involve traveling further north to explore unique destinations or checking out regional places to stay, expect delays. Planning your commute around these closures ensures a smoother, safer trip across the Bay Area.
