Accelerated Bridge Construction (ABC) makes replacing decrepit bridges quick and cheap, while slicing traffic downtime from days to hours.
The I-84 corridor that connects New York and Connecticut is getting a new and improved bridge, and the final piece of the intricate puzzle will slip into place this weekend. The way it’s happening saves money, limits closures, and could revolutionize the way America remakes its crumbling infrastructure.
The process of ABC is basically to build support structures around the existing bridge, construct the new roadway on top, then demolish the old bridge while simultaneously sliding the new bridge into place and onto its new supports.
