The Mill Dam Bridge carries Mill Dam Road across the tidal mudflat of Centerport Harbor[1] on the North Shore of Long Island, in Centerport, Suffolk County, New York. It divides the navigable waters of the harbor from the Mill Pond formed by its tidegates.[2]
The original Mill Dam and tide mill were built in 1674 at a site south of the present location. The bridge at the current location was first constructed in 1774 by Sylvanus Townsend. The mill was dismantled in 1915, and parts of it were used to construct the nearby William Kissam Vanderbilt II estate, which is now the Vanderbilt Museum.[3] The current Mill Dam Bridge prestressed concrete center span and tidegates built in 2005 replaced the span from 1936.[4] The replacement project won the 2005 American Council of Engineering Companies (ACEC) Long Island Project of the Year Award.[5]
The bridge was closed to traffic in October 2007, due to deterioration of the old causeway connecting the new span to the shore. In February 2008, workers making repairs to the causeway unearthed a 3000 pound (1400 kilogram) gear, believed to have been installed at the tide mill during an 1848 overhaul.[3] It reopened to traffic on June 27, 2008.

Historical accounts say Sylvanus Townsend built the mill in 1774 and had its machinery overhauled in 1848. In 1915, as the mill began to fall down, William K. Vanderbilt II bought beams from it for his Centerport mansion, and the town constructed a stone footbridge over the site.

GBI then removed the existing bridge and abutments, constructed new reinforced concrete abutments, a pre-stressed pre-cast bridge deck, concrete barriers, asphalt approach ramps and street lighting.
