Boston Bridge Works
Boston Bridge Works (also known as Boston Bridge Works, Inc.) was an engineering firm, building bridges throughout New England, during the late nineteenth and early twentieth centuries. Operating out of Boston, they specialized in the drafting, design and implementation of both road and railway truss bridges, a common bridge style of that period. History
The establishment of Boston Bridge Works was in the year 1876 by David H. Andrews, building notable bridges, such as the 1892 Harvard Bridge between Cambridge and Boston. The company also constructed bridges for many New England railways such as the Boston and Maine Railroad and Boston and Providence Railroad. Employees of the company were engineers and contractors for steel bridges, buildings, roofs, and railway turntables. The general offices, for most of their operating years, were at 47 Winter Street, Boston, with a plant in East Cambridge. Controversy
In August of 1909 a lawsuit was brought to the Massachusetts Superior Court claiming Boston Bridge Works and the New England Structural Company of wrongdoing in a civil suit. The suit alleged the two companies were in a collusive bidding war. The city of Boston claimed that the two companies had a monopoly in the area. Bids for the Broadway bridge consisted of  by the New England Structural Company and  by Boston Bridge Works. The contract was awarded to Boston Bridge Works but due to losing the lawsuit, they had to pay back   to the city of Boston. Dissolution
After both a fire at their Cambridge plant, and declining contracts during the Great Depression, Boston Bridge Works went out of business in 1938.
