^Looking east along Wisconsin Highway 73 from the intersection with Wisconsin Highway 80, August 2020.
Wisconsin Highway 73 is a long route that zigzags through central and south-central Wisconsin. At Albion, a tiny town just north of Edgerton, Highway 73 begins at an interchange with Interstate 39, Interstate 90, and US Route 51. From this point of beginning, Highway 73 goes north, then west, then north, then west, then north again. The first part of the route heads north through areas east of the Interstate 39 corridor, and this is where travelers on Highway 73 might reach Deerfield, Marshall, Columbus, or Princeton. Highway 73 nudges more toward the north-northwest after Princeton, so it can reach the town of Wautoma. Wisconsin Highway 73 emerges from Wautoma oriented toward the northwest to Plainfield, where the highway meets Interstate 39 and curves to a westward orientation. At Nekoosa, Highway 73 crosses the Wisconsin River and then turns north along the west bank of the river. On the west side of Wisconsin Rapids, a bridge to the east carries Wisconsin Highway 13 over the river, and that bridge drops Highway 13's traffic off on the northward roadway used by Highway 73. As Highway 13 insists on being the only road continuing northward from here, Wisconsin Highway 73 disembarks and turns toward the west. This westward portion of Highway 73 passes through farmland and the town of Pittsville. Next, Highway 73 converges with Wisconsin Highway 95 to turn northward into Neillsville. Wisconsin Highway 95 is forced to end in Neillsville at US Route 10, but Highway 73 is allowed to continue northward beyond US Route 10 to Greenwood. North of Greenwood, Highway 73 joins Wisconsin Highway 29 west to Thorp, where it jumps off the other highway to resume its northward progression. After meeting Wisconsin Highway 64 in Gilman, Highway 73 reaches its northern end. That northern end is at US Route 8 in the small town of Ingram, east of Ladysmith.
