Routing

WIS 73 starts in Dane County at an interchange with Interstate 39, Interstate 90 (Exit 160), US 51 north of the city of Edgerton. US 51 South goes into Edgerton. Also near this junction, WIS 106 meets WIS 73 east of Albion. 73 heads north 9 miles to US 12 and US 18. After a brief cosigning heading west, 73 splits north and heads 1 mile to Deerfield. About 4 miles north of Deerfield, it meets Interstate 94 at Exit 250, and continues north another 4 miles to Marshall where it has a brief cosigning with WIS 19.

It continues north about 10 miles to the city of Columbus. Just before it goes under an overpass of US 151, it crosses into Columbia County. 73 crosses US 151, WIS 89, WIS 16 & WIS 60 and US 151 again, in that order, as it travels northeast through Columbus on Park Avenue and Ludington Street. It also crosses into Dodge County just after WIS 16 & 60.

WIS 73 then continues north to Randolph. Just north of town, it crosses WIS 33. 73 will continue to go back and forth between both sides of Columbia-Dodge County Line until it crosses into Green Lake County at Hwy AW. WIS 73 continues to head north to a junction with WIS 44. The 2 routes head west through the unincorporated town of Manchester for 2 miles before 44 splits off to head to Kingston.

WIS 73 heads north another 10 miles to a junction with WIS 23, 3 miles east of Princeton. Wis 23 East heads to Green Lake. WIS 23 and 73 are cosigned to Princeton using Fulton Street and Main Street before WIS 23 splits southwest to Montello. WIS 73 then heads north-northwest, crossing into Marquette County at Eagle Rd, to Neshkoro. 73 will then cross into Waushara County just north of Hwy E, north of Neshkoro. 73 continues north-northwest 6 miles to Wautoma where it meets WIS 21. WIS 21 East heads to Oshkosh. 21 and 73 are cosigned through downtown before WIS 21 West splits off to head to Necedah.

WIS 73 heads northwest for about 15 miles to Plainfield where 73 crosses I-39 (Exit 136) and US 51 west of town. It continues now heading west, crossing in Adams County at Hwy D. 73 straddles the Adams-Portage County Line for about 4 miles. It then enters Wood County before 73 continues west-northwest to WIS 13, where it has a brief cosign with 13. WIS 73 continues west for 4 miles to the Wisconsin River where it enters the city of Nekoosa. In Nekoosa, 73 has a junction with WIS 173. 73 follows roughly along the west bank of the Wisconsin River into Port Edwards where it meets with WIS 54. WIS 54 West heads to Black River Falls. Wis 54 East is cosigned with WIS 73 along the west bank of the Wisconsin River as they enter Wisconsin Rapids's southwest side.

At Riverview Expressway (which is a regular boulevard), they meet with WIS 13.
