The major east-west route across Scott and Dakota Counties. Unfortunately, through Burnsville and Apple Valley, there is a lot of demand for commercial access from this route. The counties are studying alternate routes that could be so designated, but it is unlikely that any would fit better than this existing route. It is divided road for about 10 miles between Savage and U.S. 52 in Rosemount, and is designated as part of the National Highway System between Scott CSAH 18 and T.H. 55. The designation ends southeast of Shakopee, but could ultimately be extended westward, south of Shakopee, to intersect U.S. 169.
