WIS 69 is a major two-lane highway for the vast majority of its route, connecting the Madison metropolitan area with Monroe and, via IL 26, Freeport, in addition to serving a few smaller communities. Though WIS 69 is largely two lanes, there are two four lane segments—in Monroe along 7th Avenue and the WIS 11/WIS 81 concurrency, and approaching the US 18/US 151 interchange in Verona.
