William Preston Lane Jr. Memorial (Bay) Bridge Automated Lane Closure System Project
The Bay Bridge automated lane closure system (ALCS) is a project constructed for opening and closing lanes for two-way trafﬁc operations on the bridge. Since two-way operations were implement-ed, lane closures have been done manually. 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 will include overhead lane-use signals, dynamic message signs, horizontal swing gates, and illuminated pavement markers. These enhancements will be integrated into the existing bridge trafﬁc control system.
Work on the project, such as conduit boring and installation, began in February 2020 on the Eastern Shore and January 2021 on the Western Shore. In Fall 2022, the automated lane closure system will be in place. After the system is live, the MDTA will provide a transitional period with some manual support of the gates system to familiarize motorists to the closure scenarios.
