This interchange, located in close proximity to several area shopping malls, is among the most congested in the northeastern US. The major construction elements of this project consisted of: two new third level direct flyover ramps (325 meters long and 265 meters long); reconstruction of an existing loop ramp; widening and reconstruction of Route 4 & Route 17; and, extensive relocation of utilities. In order to minimize disruption to the traveling public, area businesses, local residents and emergency services, this extremely complex project required special attention to scheduling, MPT and communication with the public, local officials, and all other affected parties. The construction schedule of this project changed from a three-and-a-half year time frame to a 13 month super-accelerated schedule and provided for substantial incentives to the contractor – requiring an extremely experienced, knowledgeable, and flexible inspection staff.
