The Maple/Oregon Street bridge in Sturgeon Bay will be closed for part of the day Tuesday for maintenance work on the span’s locking system. The Wisconsin Department of Transportation anticipates that the bridge will be closed from 9AM until 3PM. Drivers will need to use the Bayview or Michigan Street bridge to cross from one side of the city to the other during the closure. It was pointed out that the project is weather dependent. The Maple/Oregon Street bridge opened in 2008.
