Four Overnight Closures of Highway 1 at Capitola Ave. to Start Sunday, Jan. 11

Caltrans is preparing for four consecutive full overnight closures of a single direction of Highway 1 starting Sunday, Jan. 11, 2026, to allow crews to remove temporary falsework on the Capitola Avenue bridge as part of the Highway 1 Auxiliary Lanes – State Park Drive to Bay Avenue/Porter Street | Caltrans project.  

The overnight closures will be in one direction of travel and at no time will both directions of Highway 1 be closed. Message and directional signs will be in place to alert travelers in advance of these closures and provide directions to available detours.  

On Sunday, Jan. 11 and Monday, Jan. 12, travelers on Southbound Highway 1 will encounter a full closure of the highway from 9 p.m. to 5 a.m.  

Southbound travelers will be directed to exit southbound Highway 1 at the Bay Avenue/Porter Street offramp, where they will be routed along Soquel Drive, before rejoining southbound Highway 1 at the Park Avenue onramp.  

On Tuesday, Jan. 13, and Wednesday, Jan. 14, travelers on Northbound Highway 1 will encounter a full closure of the highway from 9 p.m. to 5 a.m.  

Northbound travelers will be directed to exit Highway 1 at Park Avenue, where they will be routed along Soquel Drive and will rejoin northbound Highway 1 at the Bay Avenue onramp.  

These closures are necessary for crews to remove falsework supporting bridge and roadway elements.
