The Mystic River Bridge is significant as an example of the Brown Balance Beam Bascule, an innovative design that raised movable-bridge technology to a new level of refinement in the early 20th century. The bridge also has historical significance because it completed the State Highway Department's improvement program for coastal Route 1, Connecticut's most important "Trunk Line" highway.

I would love to hear the bridge from the point where the alarm sounds to when the arms go back up.
