I95/I495/Route #1 Interchange

The $189M project is the reconstruction of Interstate I-95/495 from Telegraph Road through the interchange of US Route 1 to the approaches of the new Woodrow Wilson Memorial Bridge. The project consists of the construction of 19 structural steel bridges, 1.6 miles of interstate roadway 12 to 14 lanes in width, 2 temporary bridges and the demolition of 7 existing bridges. Project challenges included maintenance of traffic, working in limited space in a densely populated urban area, utility coordination, coordination with contractors working on adjacent parts of the project, community relations, and environmental mitigation for adjacent sensitive wetlands.
