San Francisco County — The full weekend closure to apply polyester concrete to the WB I-80 Bayshore Freeway which began Friday, October 23, has successfully been completed, as of Monday Oct. 26., at 3:32 a.m., several hours ahead of schedule. All lanes and ramps are now open. Drivers can now enjoy a safer, smoother ride as the road is prepared for this winter's rainy weather.

The next full weekend closure on San Francisco freeways will be to complete repaving the remaining southbound U.S. 101 Bayshore Freeway (Hospital Curve) lanes between Cesar Chavez and 17th St. This is scheduled for Friday, November 6, 11 p.m. to Monday, November 9, 6 a.m. All northbound lanes will remain open during this closure weekend.

Also, crews will begin grinding operations in the weeks ahead, on the newly repaved NB U.S. 101 Bayshore Freeway (Hospital Curve) to smooth out road.

During the November 6 through 9 weekend closure:

  • All northbound lanes will remain open for public travel.
  • Motorists should avoid driving southbound 101 (Hospital Curve) due to anticipated delays.
  • Use SB I-280 as an alternate route.

**This November closure was rescheduled from an October 2-5 date.

Driver Community Benefits of Completed Work

  • Freeway corridor is now preserved.
  • Ride quality and driving comfort are improved.
