The Abandoned Pennsylvania Turnpike is the common name of a 13-mile (21 km) stretch of the Pennsylvania Turnpike that was bypassed in 1968 when a modern stretch opened to ease traffic congestion in the tunnels. In this case, the Sideling Hill Tunnel and Rays Hill Tunnel were bypassed, as was one of the Turnpike`s travel plazas. The bypass is located just east of the heavily congested Breezewood interchange for Interstate 70 (I-70) eastbound at what is now I-76 exit 161.
