FOR IMMEDIATE RELEASE
Sacramento County - Caltrans is alerting motorists that beginning next week the Isleton bridge on State Route 160 near the city of Isleton will be closed to all motorists during daytime hours into the early evening.
The bridge is scheduled for ongoing parts replacements, mechanical and electrical control system upgrades.
Bridge Work Schedule:
- November 19 to June 30, 2025 daily Monday through Saturday from 6 a.m. to 6 p.m.
- No work scheduled from November 27 - December 1 due to the Thanksgiving Holiday.
Detour:
- River Road and the Walnut Grove Bridge will be the alternate route.
- No two bridges will be closed at the same time.
Advance signage has been placed at the bridge. Caltrans urges motorists to use this detour or use Interstate 5 in Sacramento County as an alternate route. Motorists should plan accordingly and expect additional travel time.
Current truck restrictions will apply. California legal trucks having a kingpin-to-rear-axle of more than 30 feet are not recommended on State Route 160.
Additional construction is needed to maintain and keep the bridge operational. These delta bridges were originally constructed in the early 1920s and then reconstructed or refurbished in the early 1950s.
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 the Caltrans Delta Ferries website at: http://www.dot.ca.gov/d4/deltaferries/ or call the Caltrans Ferry Update Line at (510) 622-0120 for the latest information.
