History
MN 77 was authorized in 1949; and was originally numbered 36 from 1949 to 1980 as part of MN 36. The section of the route between MN 13 at Eagan and MN 62 at Minneapolis was renumbered 77 in 1980. Present dayState Highway 36 still runs from Roseville to Stillwater. From 1980 to 1985, the southern terminus of MN 77 was at its junction with Interstate 35E at the Apple Valley–Eagan boundary line. From 1985 to 1994, the southern portion of MN 77 followed McAndrews Road eastbound along its route to the Minnesota Zoo, where the route had its southern terminus. In 1985, MN 77's mile markers were calibrated with "Mile 0" at the Zoo. In the present day, the mile markers are calibrated with the zero point at the intersection of Dakota County Roads 23 and 42. Much of the original Cedar Avenue is still in existence, beginning at its intersection with Washington Avenue at the University of Minnesota and ending in Northfield, with the only major change being the upgrade of MN 77 as a freeway. Cedar Avenue is signed as Galaxie Avenue and Foliage Avenue between Eureka Township and Northfield.
