Accelerated Bridge Construction

Michael Baker is a leader in the use of Accelerated Bridge Construction (ABC) techniques, which allow for sections of a bridge to be built off-site and inserted into the existing expanse over the course of a few days, helping clients reduce road closures from months to days – or even hours – while improving worker and driver safety.

Our ABC expertise includes bridge launching, bridge slide-ins, use of precast and prefabricated elements and several of the first and the largest Self Propelled Modular Transport (SPMT) bridge moves in the United States. Our engineers also have developed ABC specifications and guidance manuals for the FHWA, such as the “Slide-In Bridge Construction Implementation Guide” and guidance for state Departments of Transportation.
