Bay Bridge Automated Lane Closure System Project

ongoing

The Bay Bridge automated lane closure system (ALCS) is a project constructed for opening and closing lanes including two-way traffic operations on the bridge. The ALCS will enhance the current manual system for motorists by allowing maintenance crews to remotely implement and discontinue two-way traffic on the Bay Bridge’s Eastern and Western Shores. The ALCS includes overhead lane-use control signals, dynamic message signs, horizontal swing gates, and illuminated pavement markers. These enhancements are integrated into the existing bridge traffic control system.
