Route description

Up until the fall of 2009, WIS 145's northern terminus was at the freeway interchange with US Highway 41 (US 41) in Richfield. A project involving the construction of five roundabouts in a less than one mile span has truncated the highway's northern terminus to the freeway interchange with US 45, with the stretch of roundabouts between US 41 and US 45 now designated as County Trunk Highway FD (CTH-FD). WIS 145 travels generally southeast through Germantown as a secondary highway. Upon reaching Menomonee Falls, the road expands into a four-lane boulevard for just over one mile (1.6 km), straddling the Waukesha–Milwaukee county line before intersecting with US 41/US 45 again.

At this point, the road heads into the city limits of Milwaukee and becomes a freeway, officially known as the Fond du Lac Freeway, though this term is rarely used locally. Although it was originally planned to continue into the heart of downtown, the freeway ends after just under five miles (8.0 km) at which point it intersects with 68th Street and Hampton Avenue. WIS 145 continues as Fond du Lac Avenue into downtown. It is a four-lane boulevard until Burleigh Street, at which point it becomes a four-lane urban arterial. It becomes a four-lane boulevard again at 20th Street until its intersection with Sixth Street. A major interchange at Interstate 43 (I-43) is just past the intersection with Walnut Street. WIS 145 turns south onto Sixth Street before terminating at the intersection with US 18 (Wells Street), adjacent to the Wisconsin Center.

History

WIS 145 was once also a part of the Park East Freeway, a short spur running east from its intersection with I-43, over the Milwaukee River before terminating at Broadway and Milwaukee Street at East Knapp Street. The freeway was demolished between 2002 and 2003, with the replacement surface streets not complete until 2006.^[2]

Fond du Lac Freeway extension

Originally, the freeway portion of WIS 145 was to extend further southeast and there was to be a major interchange located near the intersection of W. Lisbon Road and W. North Avenue, connecting the Fond du Lac with the proposed extension of the Stadium Freeway and the proposed Bay Freeway. This was never built.^[3]
