116.74, is a railroad bridge carrying Amtrak's Northeast Corridor line across the Niantic River between East Lyme and Waterford, Connecticut.

The agreement was later problematic for Amtrak and the state, as it prevented full expansion of Shore Line East service to New London.

[6] Due to these clearance issues, as well as increased reliability problems, Amtrak began planning for a replacement for the century-old bridge.

[8] As part of the project, Amtrak also replenished the beachfront and replaced the Niantic Bay Boardwalk, which had been damaged in storms several years before.

[2] Removal of the old bridge, which was crossed by a train for the final time on September 7,[2] began at the wane of the summer boating season in September, while restoration of the beach, pedestrian pathways and boardwalks in the affected area, after being delayed by Hurricane Sandy, continued until May 2013.
