The corridor carries more than 40,000 vehicles per day in each direction, and a much higher number during the summer weekends. The existing I-95 corridor is above capacity and construction of this project, while important, will cause additional traffic disruption. The goal of this Transportation Management Plan (TMP) is to evaluate the existing site conditions and provide mitigation strategies to accomplish this critical project with a minimum of safety, access, and mobility disruption. This project entails comprehensive repairs to the existing bridge deck, replacement of the wearing surface, replacement of all bridge rails with safer concrete barriers, replacement of the lighting system, and numerous other improvements. It also includes widening of the Maine approach up to Exit 3 northbound and up to Exit 2 southbound. This approach work will prepare the roadway for implementation of part-time shoulder use (allowing traffic to travel on the shoulder as a fourth lane) from Exit 7 in New Hampshire to Exit 3 northbound and Exit 2 southbound in Maine. A future project will add the ITS and remaining elements necessary to operate the Part-Time Use Shoulder. Traffic
