The Broadway Bridge, connecting Little Rock and North Little Rock in Arkansas, was replaced in 2016 using an incentivized bidding process to minimize the duration of the bridge closure. Each bidding Contractor was required to add to their base bid a cost of $80,000 per day for each day the bridge would be closed. Since the new bridge is located along the same alignment as the original bridge, the ideal sequence of completing new construction and switching traffic was not possible. Based on the winning bid proposed by Massman Construction Co., the duration of roadway closure was limited to 180 days starting the day the existing bridge was closed. The roadway closure duration guarantee was part of Massman’s $98.4M contract price. As such, the planning and sequencing of construction activities were critical to accomplish both bridge demolition and new bridge construction within the allotted time limit.
