Wisconsin Highway 145
State Trunk Highway 145 is a state highway in Milwaukee, Waukesha, and Washington counties in Wisconsin, United States, that connects the northwest suburbs of Milwaukee with the city's downtown. For much of its route, the highway is known as Fond du Lac Avenue.
Route description
Up until the fall of 2009, WIS 145's northern terminus was at the freeway interchange with US Highway 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. 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, 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 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 is just past the intersection with Walnut Street. WIS 145 turns south onto Sixth Street before terminating at the intersection with US 18, adjacent to the Wisconsin Center.
