The Lehigh Tunnel is a pair of road tunnels that carries the Pennsylvania Turnpike Northeast Extension(Interstate 476) under Blue Mountain north from Interstate 78 to the Scranton/Wilkes-Barre area between mileposts 70.7 to 71.5. I’ve driven through a few tunnels and the Lehigh Tunnel ranks with the best of them. Decently wide lanes, good markings, nice and straight, well lit. I’m impressed. It is the only road tunnel crossed by the Appalachian Trail, according to Wikipedia.
