National Tunnel Closure

During a recent inspection of the National Tunnel, Montour Trail engineers found areas of deterioration of the concrete ceiling, enough to affect the tunnel’s stability. Therefore, Montour Trail Council has decided that, in the interest of safety, the National Tunnel will temporarily close on Tuesday morning 11 November, for initial stabilization work to its deteriorating ceiling near the western entrance.  The Tunnel, located in Cecil township at MM 25, was constructed by the Montour Railroad in the early twentieth century.

The Trail Council envisions reopening the tunnel early in 2026 after the initial stabilization phase is completed. Further, more extensive renovations will occur at a date still to be determined.  The MTC does not recommend any on-road detour at this time due to narrow lanes and limited sight lines. Trail users wishing to travel west can access the trail at the McConnell Road  trailhead (MP 24.7); users wishing to head east can access the trail at Kurnick trailhead (MP 25.6). Please watch this space for further announcements about the National Tunnel, and plans for its rehabilitation and reopening.
