Scour Protection, Terminal Groin/Jetty Construction, and Beach Replenishment at Amtrak’s New Niantic River Bridge
In 2012 Amtrak replaced a 1907-era bascule bridge over the Niantic River at East Lyme and Waterford, Connecticut. The new bridge was parallel with and 58 feet south of the bridge it replaced. Its construction closer to Niantic Bay, an arm of Long Island Sound, displaced an existing recreational beach and boardwalk. Up to 27 feet of the existing beach width was impacted, with the greatest displacement occurring near the new bridge. This paper describes the wave environment and coastal processes at Niantic Bay, the design of scour protection for a railroad embankment retaining wall, the design of a restored beach and the design of a terminal groin/jetty at the mouth of the Niantic River.
