Winona's Highway 43 Interstate bridge got its annual bath Wednesday.
The Minnesota State Patrol says the annual cleaning of the bridge after the winter months resulted in some traffic slowdowns because flaggers were used to control traffic in both directions.
Crews used fresh water in high pressure pumps to spray down the gutter lines and joints, while also doing a visual inspection of the bridge, including looking for damage that might have occurred from traffic over the winter months. Sand and other materials that accumulated over the winter were also swept up prior to the spraying.
MnDOT says similar treatments are done annually on all of the Rochester district's bridges each year.
