This project involves the reconstruction of I-84 to provide a third lane in each direction between Washington Street (west of I-23) and Pierpont Road (west of I-25A) in Waterbury, CT. Work included full width shoulders in each direction; safety improvements eliminating an existing substandard “S” curve alignment; interchange ramp reconfiguration; state and local road construction and the replacement of 8 highway bridges, including 4 bridges over water courses and a pedestrian bridge over the Mad River; 7 culverts; 20 retaining walls; and rehabilitation of 5 existing culverts. The total length of the project is approximately 2.7 miles. This project is designed to decrease traffic congestion, improve traffic operations, and improve safety. The reconstructed I-84 has 12-foot-wide shoulders, three 12-foot-wide travel lanes in each direction, and is separated by a 10-foot-wide concrete barrier section. Additionally, a 12-foot-wide auxiliary lane was provided on I-84 westbound between the on-ramp from Harpers Ferry Road and the off-ramp to Hamilton Avenue. Full beneficial use of the highway was achieved 9 months ahead of schedule.
