UPDATED: Sinkhole Detected On Hank Aaron State Trail

UPDATED: The Hank Aaron State Trail has reopened between 76th and 89th streets. Repairs to fix the sinkhole are complete as of July 19, 2023.

MADISON, Wis. – The Wisconsin Department of Natural Resources (DNR) today announced the Hank Aaron State Trail will be closed effective immediately between the 76^th St. and 89^th St. access points.

Due to recent rain events, a sinkhole has formed in the trail surface. Upon staff inspection, it was determined that the hole extends multiple feet below the paved surface, creating an unsupported void beneath the asphalt layer and posing a safety concern for both trail integrity and trail users. A portion of the trail will require excavation and replacement before further use.

The non-motorized Hank Aaron State Trail extends from Milwaukee’s lakefront to the Waukesha County line utilizing both on-street and rail trail segments. Approximately 200,000 cyclists, hikers and walkers utilize the urban paved trail annually.

Various alternative routes may be used based on preference and destination. Signage for the shortest detour route will be posted at temporary barricading at the 76^th St. and 89^th St. access points and on the trail ahead of the closure. Additional closure associated with the 70^th St. bridge reconstruction is still expected on July 14, July 17 and July 18 between the 68^th St. and 72^nd St. access points.

The DNR understands the importance of the trail for recreational and commuter users and will be making emergency repairs as soon as possible to limit disruption to trail use. Upon contractor inspection and scheduling, updates to the closure dates will be posted to the Hank Aaron State Trail property page.
