Exploring Pennsylvania's abandoned highway

Pennsylvania abandoned turnpike was created by a massive 13 miles rerouting in 1968 due to congestion. These tunnels where originally built for the South Pennsylvania Railroad in the late 1800s but were never actually used until 1940 when The Pennsylvania Turnpike opened. By the elate 1950's the turnpike was heavily used and these relatively skinny tunnels were creating lots of congestion due to the bottle necking from two lanes each way into one through the tunnels. 1968 was the last year these tunnels and stretch of highway were used and they have been sitting in the woods ever since.
