The Cumberland Gap Tunnel project is a massive design and construction task combining many areas of engineering expertise with innovative construction techniques - one of the Federal Highway Administration's and National Park Service's most challenging projects to date. It includes the construction of a pair of 4600-foot-long, two-lane tunnels through solid rock and rerouting a major highway to enable the restoration of the area to resemble as closely as possible the path used by the pioneers of the late 1700's - all while adhering to ongoing concerns of safety, National Park Service interests, and the Gap's unique environment.
