Church Street South Bridge Extension
The Church Street South Extension to the New Haven Interlocking and Rail Yard project consisted of a new eight-span bridge, approximately 1,650 linear feet of reconstructed roadway, modification of two intersections, and a new 12′ x 4′ box culvert. Overall, the bridge is 1,280 feet long and 53 feet wide, providing two traffic lanes, a median, a sidewalk, and two bike lanes/shoulders. Over 1,100 concrete piles were driven to support this new bridge with the main 320-foot truss span being built entirely on the ground and lifted into place with a special 3,000-ton, high-capacity crane. The crane needed to be capable of lifting 1,031 tons of total “pick” weight 60 feet off the ground, rotating the truss 176 degrees over the rail lines, then depositing it on the waiting piers.
