Badger State Trail

Stewart Tunnel Closed Until Further Notice:
The DNR closed the Stewart Tunnel on the Badger State Trail in 2019 for safety concerns due to sections of loose and falling rocks from the ceiling and side walls inside the tunnel. The safety and well-being of trail users are of the utmost importance to the DNR. The DNR is committed to finding a path forward and has developed a Stewart Tunnel Alternatives Analysis. 
Stewart Tunnel Closed
The Stewart Tunnel has been closed since 2019.

Stewart Tunnel Alternatives Analysis

In December 2021, engineering firm GEI Consultants provided a Badger State Trail Stewart Tunnel Review of Alternatives Report for the Stewart Tunnel that analyzed nine different alternatives from an engineering standpoint. The DNR used the GEI report as a starting point for developing the Stewart Tunnel Alternatives Analysis report that analyzed a variety of considerations to formulate a recommendation.

A public comment period was conducted from April through June 17, 2022, on the draft Alternatives Analysis report. Stakeholders and the public were encouraged to submit comments using an online feedback form or in writing to the department. A total of 901 public comments were received. 

Recommendation

The Alternatives Analysis report recommends Alternative 4 – Corrugated Metal Pipe Lining – because it would provide a long-term solution for ensuring safer, year-round access to the tunnel for recreational purposes while also preserving the bat hibernaculum. Additional information regarding the recommendation can be found in the Stewart Tunnel Alternatives Analysis.
