This is the southernmost of two Mississippi River crossings for MN Highway 6. This one is located a few miles north of Crosby and Ironton. The other MN-6 crossing over the great river is a few miles upstream from Grand Rapids.

This bridge is proof that MN-DOT had building prestressed concrete girder bridges down to a science by the mid-1980s. This is a beautiful example of such a routine bridge. The river in this area has low banks, so the bridge replacement project included building up the road a few feet to prevent it from flooding. The 1984 bridge replaced a 1923 era steel truss that was built on a slightly different highway alignment. That bridge was built high enough to allow a steamship to pass under it. Another example of bridge built in a similar manner would be the Soo Line Bridge in Palisade.
