As part of the US 101/SR 25 Interchange – Phase 1 Project, the southbound on- and off-ramps at the interchange will be closed overnight on Friday, May 30, from 9:00 p.m. to 6:00 a.m. Saturday, May 31.
Please plan and follow posted detours. We appreciate your patience as we work to improve safety and mobility in the area.
When will it be closed?
The northbound Highway 25 on-ramp entrance to southbound US 101 will be temporarily closed overnight on Friday, May 30, from 9:00 p.m. to 6:00 a.m. Saturday, May 31.
These closures are necessary to safely remove topsoil adjacent to the ramps as part of ongoing site preparation work.
The temporary inconvenience serves the long-term goal of improving traffic operations and safety at the historically traffic-plagued highway interchange, addressing the current problems of higher-than-average accident rates in the interchange area and traffic backups onto southbound US 101.
