To complete critical bridge maintenance, Caltrans construction is planning a long term full closure of the southbound Appian Way Overcrossing near Interstate 80 (I-80) to replace and widen the bridge's north abutment. However, before the closure begins, Caltrans will implement a full 55-hour weekend closure of both the northbound and southbound Appian Way Overcrossing from 9 p.m. Friday, Nov. 13,through 4 a.m. Monday, Nov. 16, to install the new traffic configuration for the southbound bridge closure.

During the weekend closure, all traffic will be prohibited on the Appian Way Overcrossing. By Monday morning, the northbound bridge will be converted to two-way traffic, with one lane in each direction, to accommodate traffic during the southbound bridge's long-term closure.

The long-term closure of Southbound Appian Way OC is scheduled to begin Monday, Nov. 16, 2026,4 a.m. or once traffic configuration is complete and is expected to continue through Spring 2027.

During full weekend closures, travelers should plan to use alternate routes and take next exit.
