The Department of Transportation says it will close down the Michigan Street Bridge in Sturgeon Bay on Thursday morning, between 8AM and noon, to conduct an inspection. DOT Bureau of Structure Engineers from Madison and Northeast Region Bridge Engineers will evaluate the span’s component parts and assess needed repairs as a result of a vehicle strike on its overhead support beams. Following an analysis of its findings, the state agency will release the results of its inspection. The 85-year old downtown bridge is currently open to traffic, but remains under a weight restriction to vehicles over 20 tons. Overweight vehicles will use the Maple/Oregon Street Bridge to cross from one side of the city to the other. A signed detour is posted. After a backhoe being towed by a semi-truck struck multiple overhead support beams Friday evening, maintenance crews closed the structure to all traffic, inspected the damage and reopened the bridge Saturday with the current weight limit. A future course of action will be based on the results of the follow-up inspection.
