The Fast 14 Project in Massachusetts replaced 14 old bridges on a major highway in just 10 weekends, using innovative construction methods. The project finished ahead of schedule without any major issues, thanks to techniques like prefabricated bridge components and aggressive traffic management. The goal was to complete the work quickly and efficiently, which was achieved through close collaboration and a public awareness campaign. Temporary crossovers and a moveable barrier were used to keep traffic flowing while construction took place. Overall, the project showed that accelerated bridge construction can be a successful and cost-effective way to upgrade infrastructure with minimal disruption to drivers.
