SACRAMENTO COUNTY – Caltrans is alerting motorists that the Isleton Bridge on State Route 160 north of Rio Vista is scheduled for daytime intermittent closures beginning next week.

The bridge remains safe for travel, but additional work is needed to maintain and keep the bridge operational.

In addition to the Isleton bridge, a contractor and Caltrans structural engineers will be rotating between the Steamboat Slough and Paintersville bridges replacing structure parts, adding equipment and conduct testing through September.

No two bridges will be closed at the same time consecutively.


  • Monday, May 11 through Friday, May 15
  • 7 a.m. to 4 p.m.

All three bridges were originally constructed in the early 1920s and then reconstructed or refurbished in the early 1950s. Caltrans urges motorists to plan accordingly and use suggested detours. Current truck restrictions will apply.

During the closure, Caltrans suggests using Interstate 5 as an alternate route in Sacramento County.

California legal trucks having a kingpin-to-rear-axle of more than 30 feet are not recommended on State Route 160.

Weather conditions could delay or cancel scheduled work. Caltrans advises motorists to “Be Work Zone Alert.” For motorists using the State Route 84 Real McCoy and SR-220 Ryer Island Ferries as a bridge detour, additional ferry information is located on our Caltrans Delta Ferries website.

Bay Area motorists can check 511 SF Bay or follow Caltrans District 4 on Twitter @CaltransD4. In the Sacramento region, Caltrans District 3 will issue construction updates on Twitter @CaltransDist3 and on Facebook at CaltransDistrict3.
