The counterweighted four bar linkage type bascule bridge was designed by former Otis Elevator Company Chief Engineer Thomas Ellis Brown of New York and built in 1922 by the J. E.

Its movable span is 85 ft (26 m) wide, 218 ft (66 m) long, weighs 660 short tons (589 long tons; 599 t), and employs two 230 short tons (205 long tons; 209 t) concrete-filled counterweights.

It is operated by the Connecticut Department of Transportation and opens for approximately five minutes around 2,200 times per year, carrying an average daily traffic of 11,800. It is driven by two 1,400 pounds (640 kg) 40 horsepower (30 kW) direct current motors, and its span is greased and inspected every one hundred openings or two weeks during the winter. From May 1 to October 31, the bridge opens hourly during daylight at 40 minutes past the hour and on demand. It usually raises to let sailboats and yachts pass under.
