The Allegheny County Airport Authority board Friday approved opening up Pittsburgh International Airport to a Montour Trail extension.
The trail will be extended six miles from Enlow Road in Imperial to the airside terminal, allowing cycling enthusiasts who want to fly in or out of Pittsburgh direct access to the trail.
The 47-mile Coraopolis-Clairton trail connects with the Great Allegheny Passage to Cumberland, Md., and from there the old C&O Canal towpath to Washington.
The extension had been discussed before the Sept. 11 terrorist attacks, but was put aside because of security concerns. The trail is expected to be open by summer 2009.
