Other Tunnel Bypasses
The Abandoned Turnpike is perhaps the best-known of tunnel bypasses on toll roads. Among the other bypassed tunnels:
- The aforementioned bypass of the Laurel Hill Tunnel, which preceded the Sideling Hill and Rays Hill bypass by four years.
- The Memorial Tunnel on the West Virginia Turnpike was bypassed in 1987 to complete upgrading that highway to Interstate standards. Unlike the Pennsylvania Turnpike, the West Virginia Turnpike was built two lanes for its entire length, and needed an additional two lanes in order to get the I-77 and I-64 designations.
- The PTC considered bypassing the Lehigh Tunnel on the Northeast Extension before ultimately deciding on twinning the tunnel. Cost for the bypass and unnecessary added mileage to the highway were deciding factors.
- The PTC has been considering bypassing the deteriorating Allegheny Mountain Tunnel to alleviate traffic congestion. Boring a third tunnel is also being considered.
