State Trunk Highway 125 (often called Highway 125, STH-125 or WIS 125) is a 2.62miles state highway in Outagamie County in the US state of Wisconsin. It runs from Interstate 41 (I-41) in the Town of Grand Chute east to WIS 47 in Appleton; the route is located entirely within these two municipalities. WIS 125 is maintained by the Wisconsin Department of Transportation (WisDOT).
WIS 125 begins at a junction with I-41 and County Trunk Highway CA (CTF-CA) in the Town of Grand Chute. From here, the route heads east as a divided highway called College Avenue, passing through a business district. It meets CTF-AA (Bluemound Drive) before passing a baseball diamond. After entering Appleton, the highway meets CTF-A (Lynndale Drive). Past this junction, the route crosses the Canadian National Railway. The highway runs through a mixed residential and business area, passing to the south of Wilson Middle School. After crossing Badger Avenue, WIS 125 terminates at a junction with WIS 47; College Avenue continues east of the intersection.[2] Valley Transit's Route 15 West College bus serves much of WIS 125, including the entire eastern half of the road.[3]
