The Great Allegheny Passage (GAP) is a 150-mile multiple use rail-trail system between Cumberland, MD and Pittsburgh, PA. Completed in 2013, the GAP links to the 185-mile C&O Canal Towpath in Cumberland and provides a non-motorized, nearly level trail between Washington, DC and Pittsburgh, PA.
The trail has a compacted crushed limestone surface. Following abandoned railroad beds, the average grade is less than 1%. The steepest section is westbound from Cumberland to Deal at 1.75%. Near the Big Savage Tunnel, the trail crosses the Eastern Continental Divide.
The trail is maintained by the Allegheny Trail Alliance, a coalition of seven trail organizations in southwestern Pennsylvania and western Maryland. The group is also charged with promoting and enhancing the trail and providing maps and tourist information.
The GAP received over a million visits in 2016, an increase of nine percent over the prior year. A key feature of the GAP is the Trail Town Program® which focuses on cooperation and economic development around trail tourism and outdoor recreation. The goal is to ensure that trail communities and businesses maximize the economic potential of the region’s trails, while working to improve the connections between trail and town.
A 2008 study of the trail found that, on average, business owners indicated that one-quarter of their gross revenue was directly attributed to trail users. A 2014 survey found that 62% of trail users included an overnight stay and spent an average of $124.58. This has increased by $26 since the 2008 trail user survey. The average day user spends roughly $18.
A popular feature is the Big Savage Tunnel, the longest of three major tunnels along the route. The 3,294-foot tunnel was built in 1911-12 through Big Savage Mountain near the PA-MD border. Last used by the railroad in 1975, the flooded and damaged tunnel was the major obstacle to getting over the mountain between Frostburg and Meyersdale. To have the tunnel drained, repaired, stabilized, and developed for trail use cost nearly $13 million. It was officially reopened in 2008.
The GAP can trace its beginning to 1978 when the Western Pennsylvania Conservancy purchased the first section of right-of-way from the Western Maryland Railway. In 1986 the first of many rail-trail conversion projects route opened 9.5 miles of trail in Ohiopyle State Park. In June 2013, thirty-five years after construction first began, the final GAP section was completed (from West Homestead to Pittsburgh) at an overall cost of $80 million.
