Theme 1: Structure and Process
One of the costs of any road project is the economic impact of rerouting traffic during the construction. Methods that minimize the disruption will reduce costs and often improve safety. Accelerated Bridge Construction (ABC) methods include prefabricating as much of the bridge as possible at an off-site location. Large parts are brought to the site and installed according to a plan that minimizes the time required to reroute traffic.
