The new precast concrete box culvert/bridge on Michigan’s M-142 over Phillip Drain exemplifies Accelerated Precast Construction (APC) to quickly replace culverts and small bridges in ways emulating ABC (Accelerated Bridge Construction). The award-winning M-142 project in 2014 called for removal of the existing bridge, installation  of a cofferdam with sheet piling, installation of a 48-foot long by 24-foot wide by 12-foot tall precast concrete box structure, all associated end treatment, and all associated road reconstruction. The project had a completion date of 14 days, regardless of the weather. Minimizing user delays and traffic disruption were a priority for MDOT, as M-142 is the major artery in the area.
