Folks who use the Michigan Street Bridge in Sturgeon Bay will have to find another route to travel for several days next week. The Department of Transportation says the more than 80-year old span will be closed on December 4th as part of a continuing project to repair bridge beams damaged in a couple of vehicle strikes. Work crews are expected to heat straighten seven beams overhead. One beam will be entirely replaced. The span is not expected to be re-opened to vehicle and pedestrian traffic until the end of the week. The state agency says repairing the bridge at this time of year lessens the impact for marine and motor vehicle traffic. All of the repair work is weather dependent. The bridge will continue to open for marine traffic while repairs take place. The span is not expected to be re-opened to vehicle and pedestrian traffic until December 12th.
