Hadlock Brook Bridge (1926) was the eighth of 17 bridges constructed along 57 miles of carriage road on Mount Desert Island between 1917 and 1940.

It is one of three smaller masonry bridges with a single arch in Acadia that was modeled after a bridge at the end of Swan Lake in Central Park. Unlike its sister bridges, the parapet walls curve toward the upstream side to follow the road.

The cost of construction was estimated to be $6,983.60.
