Mystic River Railroad Bridge

The Mystic River Railroad Bridge is a steel truss structure carrying two tracks of the Amtrak Northeast Corridor across the Mystic River between Groton and Stonington townships. The structure can open to allow ships to pass, creating a functional meeting point between rail and water traffic.

The current structure was built in 1984 and replaced a steel swing bridge from 1875, which in turn had succeeded an original wooden drawbridge from 1819. This progression reflects how infrastructure repeatedly adapted to the demands of evolving transportation.

The bridge is woven into daily life for commuters traveling between coastal communities and demonstrates how rail transport became essential to the region. Passing trains punctuate the rhythm of the place and link people to broader transportation networks.

The structure is visible from the riverbank and nearby roads, allowing visitors to watch its mechanical operation when it opens. The best times to observe activity are during peak travel hours when trains pass more frequently.

The structure holds the distinction of being the easternmost movable bridge on Amtrak's Northeast Corridor section within Connecticut. This boundary status makes it a notable marker between two different infrastructure networks.
