McKnight Road Bridge
Posted August 15, 2012, by John Marvig

Personally, I am amazed the bridge still stands. It was closed in February of 2009 and was supposed to be removed this year.

The bridge is the oldest highway bridge in Carver County, and one of the oldest railroad related bridges in the county. It is our last historic bridge as well. Sadly it will be removed.
