NORWALK, Conn. -- Terracon will partner with HNTB to provide geotechnical services and geotechnical laboratory services for the $465 million Walk Bridge project in Norwalk, according to a press release.
The project involves the replacement of the 118-year-old Walk Bridge, a movable railroad bridge that crosses over the Norwalk River.
In 2014, it failed in the open position twice, which halted Metro-North and Amtrak traffic on one of the busiest rail corridors in the United States.
Terracon’s role in the project includes providing site characterization involving land- and water-based borings, according to a press release.
The Walk Bridge, one of only two remaining swing bridges in the Northeast rail corridor, will be replaced with a bascule-type drawbridge, which hinges on one side and is raised with the assistance of counterweights. The bridge will carry four sets of tracks on two side-by-side bridge segments, allowing one side of the bridge to operate while the other is being assessed, according to a press release.
“We are pleased to be working with HNTB on this important project,” said William Johnson, client development manager for the New England division, in a press release. “Terracon was selected due to our experience with this type of site characterization, and our ability to perform all necessary services in-house.”
Terracon is an employee-owned engineering consulting firm with more than 3,500 employees providing environmental, facilities, geotechnical and materials services from more than 150 offices in 42 states, according to a press release.
