SACRAMENTO COUNTY – Caltrans is alerting motorists that three delta bridges on the Sacramento River will be closed nightly.

Beginning October 1, the Iselton, Three Mile Slough and Paintersville bridges in rural south Sacramento county along State Route 160 will begin alternating overnight bridge closures.

With continued delays to motorists due to these bridges being stuck in the upright position extensive inspections, testing and parts replacement are required so that they operate more efficiently.

The Rio Vista Bridge on Highway 12 and west of Highway 160 will remain open with the current nighttime work schedule using one-way traffic control.

These bridges remain safe for travel. The bridges have a dated design and in some cases are more than 75 years old. A contractor and structural engineers will need to refurbish electrical and mechanical equipment at each of these locations.

Vehicle traffic is open during daytime hours for all bridges. Boating traffic is closed at Three Mile Slough bridge.

Isleton Bridge

  • 9 p.m. to 5 a.m. October 1, 2, 3, 7, 8

Three Mile Slough Bridge
