SACRAMENTO COUNTY – Caltrans is alerting motorists that three bridges along the Sacramento Delta on State Route 160 are scheduled for daytime intermittent closures. All bridges remain safe for travel.

Additional work to maintain and keep these bridges operational is needed. A Caltrans contractor and structural engineers will be replacing bridge parts and conduct testing on the Isleton, Steamboat Slough and Paintersville bridges through September.

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


Beginning April 20 through September 20.

Intermittent Closures are Monday – Friday 7 a.m. to 4 p.m.


All three bridges were originally constructed in the early 1920’s and then reconstructed or refurbished in the early 1950’s. 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.
