Due to deterioration of the National Tunnel’s concrete ceiling, the Montour Trail Council has closed the National Tunnel in Cecil Township. The tunnel, at trail mile marker 25, is the Montour’s longest tunnel at 623 feet. The Montour Railroad built the tunnel in the early 20th century.

“The Montour Trail Council understands closing of any part of the trail affects trail users and only undertakes this step for the safety of all of us,” said MTC President Julian Wolfe. “Rehabilitation of this landmark tunnel will take time and considerable fundraising. We trust trail users will support our efforts.”

Initial stabilization work on the ceiling near the western entrance has begun. The trail council, which owns and manages the Montour Trail, envisions reopening the tunnel in early 2026 after the stabilization phase is completed.

More extensive renovations will occur at a date still to be determined.

The MTC does not recommend any on-road detour due to narrow lanes and limited sight lines. Trail users wishing to travel west can access the trail at the McConnell Road trailhead (mile marker 24.7); users wishing to head east can access the trail at Kurnick trailhead (mile marker 25.6).
