Description: In 2020 the Arkansas Department of Transportation (ARDOT) completed the replacement of two bridges over De Roche Creek on I-30 near the city of Arkadelphia. ARDOT partnered with Michael Baker International to provide design and plans for Arkansas’ first lateral slide highway bridge replacement. I-30 is a heavily trafficked route that connects Little Rock, AR to Dallas, TX, so using ABC was the ideal solution to reduce lane closure time and improve safety. The new steel plate girder superstructures were erected on temporary falsework outside of the existing parallel bridges, while crews constructed the permanent semi-integral straddle bent substructure underneath the existing bridges, supported on drilled shafts. This approach limited traffic disruption to two short-term periods, eight days each, during which traffic was reduced to a single lane in each direction. The single span arrangement served to simplify the slide process and reduced the environmental impact on De Roche Creek. The presentation includes design and construction details as well as lessons learned.
