Louis Berger’s long-span bridge division, Ammann & Whitney, earned the prestigious Diamond Award for its trailblazing dehumidification techniques on the William Preston Lane, Jr. Memorial Bridge, also known as the Chesapeake Bay Bridge.
The first of its kind in North America, the dehumidification and rewrapping of the main cables and anchorages of the bridge halted corrosion and significantly extended the unique dual-span structure’s life. Also a winner of an Engineering News-Record (ENR) 2016 Highway/Bridge Best Project award, the landmark project featured innovative dehumidification techniques, including a robust supervisory control and data system that allows for regular, remote monitoring of cable and plantroom conditions.
The award was presented at the 50th annual ACEC-NY Engineering Excellence Awards gala held in New York City in April, 2017. Each year, dozens of projects are submitted to ACEC-NY’s panel of experts who judge according to a rigorous set of criteria, including complexity, innovation and value to society. The top-level award is the Diamond Award, presented only to the most outstanding engineering projects in the region.
