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.
