Project Summary

This project involves the installation of an Automated Lane Closure System (ALCS), consisting of integrated Intelligent Transportation System (ITS) devices that inform motorists of closed lanes as they approach the eastern shore two-way traffic crossover. The system will be utilized by the William Preston Lane Jr. Memorial Bridge (Bay Bridge) operations and maintenance staff to remotely close lanes, allow contra-flow operations on the North or South bridges, and address incidents. Aldridge is wrapping up work on the installation of an ITS system that will integrate in-pavement lighting with swing gates, overhead lane use, and digital messaging signs to switch traffic patterns during high traffic periods remotely. 

This impressive project boosted:

  • 8,500 LF - Guardrail Installed

  • 2,000 CY - Concrete Poured

  • 627 In-pavement LEDs

  • 420 Lane Closures

  • 53 Foundations
