The bridge deck hangs 26 meters above the Eggemoggin Reach. The two-lane State Route 15 crosses the bridge. It is the only connection to Deer Isle. The bridge is toll-free.


The bridge was built in the late 1930s and opened to traffic on December 31, 1939. The bridge replaced a ferry service and was the first permanent connection to Deer Isle. The bridge was built using the same engineering as the Tacoma Narrows Bridge, which collapsed in 1940. The Deer Isle Bridge also had the same high wind stability issues, and was later modified to avoid the danger of collapse. The bridge deck was replaced in 2008.
