Early Morning Northbound I-280 to Southbound SR-1 Ramp Closure on March 29
Published: Mar 26, 2026
San Mateo County ― Caltrans will close the northbound I-280 ramp to southbound State Route (SR) 1 in the early morning hours of Sunday, March 29, from 2 a.m. to 8 a.m. Crews will place temporary K-Rail, a barrier that shields construction workers from the dangers posed by active traffic, so that they can make emergency repairs.
Detour: Take the Junipero Serra off-ramp, turn left on Junipero Serra Blvd., turn left on San Pedro Rd., turn left on Sullivan Ave., and enter the southbound SR-1 on-ramp.
Please follow detour signs and drive with caution. All work is weather dependent.
Thank you for your patience as we work to maintain our state's highways, bridges, and tunnels.
