The massive construction site is taking shape for the Walk Bridge project, with super-size equipment on the scene along the Norwalk River. The $1 billion multi-year project to build a new railroad bridge requires the installation of eight 12-foot drilled shafts, varying between 80 to 100 feet in depth, according to a Facebook post from the state Department of Transportation on Oct. 9. Over the last decade or more, the bridge has failed dozens of times to “swing” properly between allowing rail travel to go across it and nautical traffic to go in and out of Norwalk Harbor. After the bridge failed twice in a two weeks in May and June 2014, DOT decided it was time to replace the structure. After nearly a decade of work to do plans and secure state and federal funding, the Walk Bridge Replacement project broke ground in 2023, with the demolition of the Maritime Aquarium’s IMAX theater beginning that March to make space for the project site. The Walk Bridge replacement project is anticipated to be completed by 2029, according to DOT.
