This story is part of a bi-weekly series that celebrates people who are reaching across a divide to "build bridges" with those different from themselves. The Sparkt Bridges series is made possible with the support of UPMC.

Lots of people have big dreams. But only exceptional people have the vision to make them come true.

Linda McKenna Boxx is one of those people.

Linda led the effort to create something that almost a million people enjoy every year: a continuous "rails-to-trails" hiking and biking trail system, built along abandoned railroad rights-of-way, that allows people to bike from downtown Pittsburgh all the way to Washington, DC, and lots of places in between.

Linda Boxx (L) has ridden the trail from Pittsburgh to Washington, DC three times!

The task wasn't easy. Linda leveraged her position at Western Pennsylvania's Regional Trail Corporation to persuade hundreds of community leaders, lawmakers and financial supporters to join forces behind a multi-million dollar project that united a fractured a system of community rails-to-trails attractions into one amazing 335 mile ride.

No one was sure it would succeed. But Linda was confident it could be done. What she and the volunteers have accomplished is a great reminder that by working together, we can build something bigger than ourselves.

Linda's coalition-building resulted in the formation of the Allegheny Trail Alliance. The Alliance worked to link trails in Western Pennsylvania, creating the Great Allegheny Passage, and to connect the "GAP" to the C&O Canal Towpath trail in Maryland, which takes the trail on to D.C.

Now, every year , thousands of people complete the full trip from Pittsburgh to our nation's capital, and hundreds of thousands of others enjoy day trips along sections of the trail.

The rebuilt train station along the trail at West Newton, PA was one of the Regional Trail Corporation's big projects.

For Linda and the volunteers who were involved in creating this amazing recreational marvel (my dad Jim Linaberger was Linda's fundraising partner back when this all started) it's a source of great pride. "It was a joy to be able to do that," said Linda.
