According to the Milwaukee Road Archives, this bridge was built in 1913 reusing a railroad span from bridge Z-1154 along the Iowa division.

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.
