Bay City historic landmark mistakenly destroyed

      The last standing remnant of a company that historians say helped establish Bay City has been torn down in a construction mishap.

      Last week, a contractor mistakenly took down a 20-foot-tall guard tower that once stood at the entrance to the former Industrial Brownhoist complex. Preservationists say the structure likely was more than 100 years old.

      Crews are working on a new development project at the site.

      The person responsible says he feels badly about it.

      Steve Birnbaum is the president of American Excavation, a Saginaw-based construction company serving as a contractor at the Uptown Bay City site. He says he was operating a 150,000-pound excavation machine while yanking out a nearby fence.

      Birnbaum tells (

      ) he wasn't careful and "really stuck" his nose into something he "shouldn't have."
