BvF provided construction inspection services for the installation of an Automated Lane Closure System (ALCS) on the William Preston Lane Jr. Memorial Bridge (Bay Bridge) in Queen Anne’s County. This project involved the implementation of a series of integrated Intelligent Transportation System (ITS) devices to advise motorists of closed lanes and support contra-flow operations.
Key components included:
- Installation of full matrix color dynamic message signs (DMS) and enhanced lane use signs (ELUS) on overhead gantries.
- Four full matrix color DMS for ALCS warning messages for contra-flow operations.
- Gates of various types and lengths to close lanes on the approach to the eastern shore two-way traffic crossover.
- Illuminated pavement markers activated during crossover operations.
The scope of work included:
- Furnishing and installing ALCS ITS equipment and necessary controllers.
- Replacement of all lane use control gantries on the eastern shore and installation of three new gantries.
- Installation of gate control shelters and maintenance driveways.
- Replacement and installation of new W-beam traffic barriers and new concrete barrier sections.
- Signing, marking, and maintenance of traffic.
- Lighting/electrical and ITS modifications.
- Stormwater management facilities, landscaping, and erosion and sediment control.
- Coordination with MDTA for ITS integration.
This comprehensive project significantly improved traffic management and safety on the Bay Bridge, ensuring efficient lane closures and supporting contra-flow operations.
