quick_answer: Quick answer: Sacramento to San Francisco is about 90 miles on I-80 — roughly 1 hour 40 minutes when both bottlenecks are clear, commonly 2 hours 15 minutes to 3 hours 30 minutes at the weekday westbound peak. Leave 9:30 a.m.–2:00 p.m. Avoid 6:30–9:00 a.m. westbound. The Yolo Causeway (miles 5–15) and the Bay Bridge approach decide the trip. If the causeway breaks, take I-5 north to Woodland then Highway 113 south.

faqs[5]{q,a}:
  How long does it take to drive from Sacramento to San Francisco?,About 90 miles. Free-flow is roughly 1 hour 40 minutes. Weekday westbound peaks commonly run 2 hours 15 minutes to 3 hours 30 minutes when the Yolo Causeway and Bay Bridge both stack.
  What is the best time to drive from Sacramento to San Francisco?,9:30 a.m. to 2:00 p.m., or after 7:00 p.m. Avoid 6:30–9:00 a.m. westbound. Before 5:30 a.m. is free-flow if you can leave that early.
  What should I do if the Yolo Causeway is jammed?,Leave it. Take I-5 north to Woodland, then Highway 113 south to rejoin I-80 near Davis. Locals also use this bypass routinely in the 2:00–6:00 p.m. band.
  Does the Capitol Corridor go to San Francisco?,No. Trains serve Sacramento to Oakland/Emeryville (typically 1 hour 45 minutes to 2 hours). You connect into San Francisco by Amtrak Thruway bus or local transit.
  Is weekend I-80 easier?,Not reliably. Caltrans flags recreational weekend travel on I-80 and US 50. Saturday mornings and Sunday afternoons carry real volume, especially Tahoe-bound eastbound traffic.
