MARIN AND CONTRA COSTA COUNTIES — OCTOBER 18, 2026. Travelers on the Richmond–San Rafael Bridge should prepare for lane closures on eastbound Interstate 580 beginning Monday, October 19, 2026. According to Caltrans, the work involves cleaning and repainting structural steel to protect the bridge, with restrictions occurring during daytime and overnight periods. The broader project is tentatively scheduled through December 29, 2028.

Which direction is affected?

The October 15 Caltrans notice specifies eastbound I-580, the direction toward Richmond and Contra Costa County. This announcement does not describe a continuous full closure of the bridge or a blanket shutdown of westbound lanes. Drivers traveling to work or making trips between Marin and the East Bay should check the actual day and time of their crossing.

When will lanes close?

Caltrans gives two scheduled restrictions on the eastbound span: one lane closed from 7 p.m. until 2 p.m. and a more restrictive two-lane closure from 9 p.m. until 6 a.m. within the announced Sunday-through-Thursday work pattern. Because this schedule spans overnight and extends into daytime, a morning or lunchtime trip can also be affected; these windows are not exclusively late-night restrictions.

What are crews doing?

Teams will install suspended work platforms and protective containment around portions of the structure, remove existing paint and apply new coatings to bridge steel. The goal is preservation and corrosion protection. Painting work on an active bridge requires protective access equipment and traffic controls to reduce risk to workers and travelers.

Why could this take years?

The state describes a long-term bridge maintenance project with an estimated work window from October 19, 2026, to late December 2028. The end date is tentative. It does not mean a lane will be closed continuously for more than two years; restrictions are scheduled around work phases and operational conditions. Weather, marine exposure and contractor logistics may change the pattern.

How commuters can prepare

  1. Check eastbound I-580 traffic shortly before departure, especially before morning peak travel.
  2. Allow time for slower merging near work zones.
  3. Avoid sudden lane changes and follow electronic message boards.
  4. Do not assume that a 6 a.m. end for two-lane restrictions means every other lane restriction has ended.
  5. Review official Caltrans updates before important medical appointments or airport connections.

The Caltrans October 15 advisory gives the planned work windows. Use QuickMap for current travel conditions and 511 Bay Area for other regional transportation information.

What changes for residents?

The immediate effect is reduced bridge capacity at certain times beginning October 19. Marin and East Bay commuters should build flexibility into eastbound trips as preservation work starts. For related regional roadwork, California58 also covers SR‑37 Petaluma River Bridge traffic reductions.
