The Deer Isle suspension bridge, crossing Eggemoggin Reach, opened in 1939 to connect the island to the mainland and replace the ferry system that was considered antiquated and dangerous. Its total length is 2,509 feet. The bridge was built as a WPA project and designed by renowned suspension bridge engineer David B. Steinman. Though Steinman’s work was generally highly regarded, the Deer Isle bridge design contained a flaw: the stiffening girder was too shallow for the length, likely for economic reasons. After the collapse of Washington’s Tacoma Narrows Bridge in 1940, Steinman returned to stiffen the girders of the Deer Isle Bridge by adding a system of cable and floor stays while maintaining the original girders. Tolls were charged on the bridge until 1961.

The caption reads, "Deer Isle, Sedgwick, Maine, Bridge."
