State Trunk Highway 99 (often called Highway 99, STH-99 or WIS 99) was a state highway in the U.S. state of Wisconsin. It ran east–west between Eagle and Mukwonago. The road was turned over to Waukesha County maintenance in 1999, and is now County Trunk Highway LO (CTH-LO). The designation was chosen to honor Lloyd Owens, long-time Waukesha County Board Chairman.
