Barton Bandemer Pedestrian Tunnel

We’re excited for completion of the Barton-Bandemer Pedestrian Tunnel—a key connection under the railroad that will link Bandemer Park to Huron River Drive and the Barton Nature Area along the B2B Trail on Ann Arbor’s northwest side.

On March 24, 2025, the City of Ann Arbor broke ground on the tunnel that now passes beneath the MDOT railroad operated by Amtrak. From June 3–5, crews took advantage of a scheduled train service pause to complete a 48-hour, round-the-clock operation to install the main tunnel structure.

The city is partnering with Washtenaw County Parks and Recreation Commission and the county’s non-profit partner, Huron Waterloo Pathways Initiative (HWPI), on this project to extend the B2B Trail westward through Barton Nature Area. The pedestrian tunnel connects the new segment of the B2B Trail in Barton Nature Area — which was completed in summer 2024 — with the existing B2B Trail network in Bandemer Park and more than 20 miles to the east. 

We completed this project ahead of schedule and opened to the public in November of 2025. Check out the City of Ann Arbor’s project website for the most updated project information and trail access restrictions in place in case of maintenance.
