Caltrans is reminding motorists that one-way traffic controls will be in effect on the Highway 160 Antioch Bridge as crews perform routine inspections of the span this week and next week. Crews will alternate lane closures in both northbound and southbound directions, with flaggers and a pilot car helping direct traffic. The work is slated from 9 a.m. to 2 p.m. on four consecutive weekdays – Monday through Thursday of this week and March 16 to 19 next week. This will allow one traffic lane on the bridge to remain open during the inspections. Motorists should expect delays and allow for extra travel time. Work is dependent on the weather. Vessels will pass normally beneath the bridge on the San Joaquin River.
