Route 2 Safety Improvement Project, Bridges Nos C-19-024, C-19-035 at Crosby's Corner, Boston, MA

Louis Berger served as lead designer and managed project provided civil, traffic, structural, environmental, right-of-way, drainage professional design and construction phase services. To eliminate the traffic congestion and dangerousness of the signalized four-legged intersection of Route 2/Route 2A at Crosby’s Corner, a unique grade separated diamond interchange design with limited access roadway was built. Key issues included wetland replication and construction of stormwater wetlands; design of 1.5 miles of gravity and cantilever retaining walls that vary in height up to 30ft; and landscape design keeping with the historical, semi-rural character of the area.
