St. Louis River Bridge
Posted December 1, 2011, by John 'JT' Lamb (bigbearjt [at] gmail [dot] com)

An oddity: This bridge links two states WI and MN. Due to an error, MN-23 crosses into Douglas County, WI for about a quarter mile. It is an unsigned crossing as the road is fully maintained by MnDOT.
