SACRAMENTO COUNTY – Caltrans is alerting motorists that the Three Mile Slough Bridge on State Route 160 is scheduled for partial nighttime closure to complete prep work for additional parts replacement. The bridge remains safe for travel.

For safety the bridge will be under daily one-way traffic control from 8 p.m. to 6 a.m.  June 22 - 27.

A contractor will be working to install reinforcement members on the lift span. This is necessary for the replacement of the sheave bearings and to machine the trunnion in both towers.

Caltrans urges motorists to plan accordingly and to expect delays. Current truck restrictions will apply.

Caltrans suggests these alternate routes:

•           For detours involving Sacramento County origins/destinations, motorists may consider using Interstate 5.

•           For other detours, motorists may consider using State Routes 12, 4, and 160 along with segments of Interstates 80 and 680.

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..
