It carries vehicle and foot traffic directly into the tourist district of town via {{convert|33|ft|m|abbr=on|adj=mid|-wide}} Main Street (U.S. Route 1). HistoryThe Strauss Heel-trunnion type bridge was designed by former Otis Elevator Company Chief Engineer Thomas Ellis Brown of New York and built in 1920 by the J. E. FitzGerald Construction Company of New London, Connecticut, according to its historical marker. Its movable span is {{convert|85|ft|m|abbr=on}} wide, {{convert|218|ft|m|abbr=on}} long, weighs {{convert|660|ST|LT t|0|abbr=on|lk=on}}, and employs two {{convert|230|ST|LT t|0|abbr=on}} concrete-filled counterweights. Until 1928, the bridge carried streetcars of the Groton and Stonington Street Railway. 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 {{convert|1400|lb|kg|lk=on}} {{convert|40|hp|kW|lk=on}} direct current motors, and its span is greased and inspected every 100 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.[1] PicturesSee also
