Twin Cities highway that runs through the southern suburbs, mainly following the southern border of Minneapolis. It is 62nd Street on the Minneapolis grid system; this is why it was called County Road 62 when it was built by Hennepin County. When Hennepin County and the state of Minnesota swapped some Twin Cities highways, they decided to keep the "62" designation, calling it MN-62. Of course, there already was a MN-62, but since it's rather a long way away from the Cities, nobody gets confused.
You won't find "Crosstown" on any signs, but people always call it that.
