Drawbridge Operation Regulation; Black River, Port Huron, MI

The Coast Guard proposes to modify the operating schedule that governs the Military Street Bridge, mile 0.33, the Seventh Street Bridge, mile 0.50, the Tenth Street Bridge, mile 0.94, and the Canadian National Railroad Bridge, mile 1.56, across the Black River at Port Huron, MI. The City of Port Huron requested the winter hours to be expanded for City-operated highway bridges. We have reviewed the regulation in its entirety because the current regulation is approximately 30 years old, use of the waterway has substantially changed, and the current language and conditions in the regulation are difficult to follow and understand.
