Groton Bridge Company
# Groton Bridge Company

The Groton Bridge Co. was an American construction company.

## History

The company was founded in 1877 as Groton Iron Bridge Company, by merger of two firms. It was reorganized and became the Groton Bridge and Manufacturing Company in 1887. It was purchased by the American Bridge Company in 1899 but was separated in 1902 as Groton Bridge Co. and survived under that name until the 1920s.

The firm was believed to be a subsidiary of American Bridge Co. in 1908 when it installed two Parker truss spans manufactured by American Bridge Co. to complete the Plata Bridge in Puerto Rico.
