Continental Bridge Co. from Alexandria Mn. didn't exist until some time in the 1980's. Prior to this a Continental Bridge Co. existed in Peotone Illinois with it's headquarters in Chicago. This was from 1903 - 1948. The assets of the company were bought by Bennett Industries who continued bridge and structural work until 1977.
