Overview
- Caltrans closed the westbound Alfred Zampa Memorial (Carquinez) Bridge Friday night for a deck repaving project that will keep the westbound span and its pedestrian and bike path closed through early Monday morning.
- Officials directed westbound I‑80 traffic to detours using southbound I‑680, the Benicia Bridge and westbound Highway 4 while keeping eastbound I‑80 open.
- Two lanes in each direction on Highway 101’s Hospital Curve in San Francisco were reduced starting Friday night for median work and drainage upgrades that are part of a 2025 stabilization project.
- San Francisco Bay Ferry added extra Vallejo-route trips and Caltrans urged drivers to use alternate routes or public transit because queuing is expected on I‑780, I‑680 and the Benicia Bridge.
- Coverage shows slight discrepancies in reported start times and total hours but all outlets say the closures are scheduled to end by about 3 a.m. Monday, so commuters should plan for multi-hour delays and altered travel plans.
