Michael Baker International’s Post

Interstate 30 is a heavily trafficked corridor that connects Little Rock, Arkansas, to Dallas, Texas. In Southwest Arkansas near the city of Arkadelphia, two aging bridges on this thoroughfare provided passage over the De Roche Creek. In 2017, the time had come for the crossings to be replaced due to almost continual repairs being needed. The Arkansas Department of Transportation (ARDOT) and Michael Baker International utilized an innovative Accelerated Bridge Construction (ABC) method known as a lateral slide to replace the existing structures. This was notably the first time that a lateral slide had been used in Arkansas. Under this method, the new bridge superstructures were constructed next to the existing bridges on temporary falsework. Once complete, the existing bridges were demolished, and the new bridges were slid into place. The new bridges now accommodate three lanes of traffic in each direction, allowing more people and goods to pass over the creek and reducing delays, which can have economic benefits while also reducing emissions and travel times.
