Milepost Conversion

In 2006 the Great Allegheny Passage received a unified mileage system that provides a single set of mileposts beginning in Cumberland and counting toward Pittsburgh. Previously the trails were numbered individually, sometimes in different directions. The new mileposts may be adjusted a little when the trail is complete, but they’re accurate enough for planning purposes. This table shows the locations of places along the trail and the conversion between the new and old mileposts, together with the trail distance from Washington DC.

The new mileage system measures distances through the Pinkerton Tunnel, which is currently closed. An interim trail runs around the Pinkerton Neck; the interim trail is about a mile longer than the final trail will be. As a result, the trail mileage between Markleton and Ft Hill is about a mile longer than the mileposts suggest.
