Caltrans is scheduled to close one direction of Interstate 680 at the I-680 and Mission San Jose (SR-238) Separation/Overpass in Fremont for critical bridge and pavement work.
Northbound I-680 will close the weekend of Aug. 8.
This 55-hour closure is necessary to safely and efficiently complete key construction activities, including full bridge deck resurfacing and approach slab repairs. This phase of work involves heavy machinery and the resurfacing of the entire bridge deck.
Only one direction of travel on I-680 will be closed with detours set in place.
Motorists heading northbound on I‑680 through Fremont should follow this recommended detour:
- Exit right onto the Mission Boulevard / SR‑238 off‑ramp.
- Turn left to continue on northbound Mission Boulevard (SR‑238).
- Continue on Mission Boulevard until Niles Canyon Road (SR‑84) and turn right.
- Re‑enter I‑680 via the northbound SR‑84 on‑ramp toward Sacramento.
Caltrans thanks the public for their patience and cooperation as we continue to improve California’s transportation network.
