Talk:Keystone Bridge Company

looking
Does anyone know if there is a website that shows a list of ALL the bridges contructed by "Keystone"? I'm trying to find information on a bridge that was located in my hometown of Republic, Michigan. It was torn down in either 1985 or 1984. It would've been built around 1900.71.206.103.89 (talk) 22:25, 19 October 2009 (UTC)
