V. Roth, Jr. Bridge
St. Georges, Delaware
Owner: Delaware Department of Transportation
Design / Construction Engineering and Inspection: FIGG
Originally known as the Chesapeake and Delaware Canal Bridge, this 4,650’ long bridge was the first concrete segmental cable-stayed bridge in the northeastern United States. The 750’ main span uses the same superstructure cross-section as the 150’ approach spans by incorporating precast delta frames for stay anchorages. The bridge main span has a vertical clearance of 138’ and was erected from above in unidirectional cantilever without interruption to canal traffic. These innovative design solutions saved the Delaware Department of Transportation over 10% compared to bids for the alternate design.
