Key Facts:
The 4,650’ long Senator William V. Roth Jr. Bridge (originally the Chesapeake & Delaware Canal Bridge) spans the Chesapeake & Delaware Canal near St. Georges, Delaware. This was the first cable-stayed bridge in the northeastern United States and features the longest precast concrete span in the northeast at 750’. The innovative design solutions used in the bridge saved the Delaware Department of Transportation over 10% compared to bids for the alternate design.
The 750’ long main span has a 138’ vertical clearance and was erected from above in one-directional cantilever without interruption to canal traffic. The main span uses the same superstructure cross-section as the 150’ approach spans by incorporating precast delta frames for stay anchorages. This streamlined construction for the best efficiency.
