- The Allegheny Mountain Tunnel carries the Pennsylvania Turnpike (Rt. 76 & Rt. 70) through the Allegheny Mountains. The tunnel was built in 1939 and is 6,070 ft (1.85 Miles) long, it was the longest tunnel at that time, and considered an "engineering marvel". The tunnel is used by 11 million vehicles annually today.
Throughout the 2000s, state officials attempted to implement plans to replace the tunnel, citing its age.
Pennsylvania turnpike tunnels that was a difference between the four constructions that was awesome wow.
Construction of the bypass is now underway. They've started excavation about three quarters of the way down the mountain, following the old South Pennsylvania Railroad grade.
The bypass is slated to use a cut instead of a new tunnel, so hazardous materials loads will no longer have to exit the turnpike and take Route 31 over the mountain between Bedford and Somerset.
Bypass isn’t started yet current construction is for widening and eliminating turns. Bypass is scheduled to start after the current construction is completed
That can't be pa the sky is too blue
@@twinheatingairconditioning135 Yes you are correct. 😊
in the left lane, afraid to pass blocking traffic....
6,070 feet is 1.15 miles, not 1.85. The original 1939 Allegheny tunnel still stands (just south of this one) and is heavily secured by the Ganassi racing team who use it for testing.
That’s the laurel hill tunnel
I don't understand why it's such a big deal,the liberty tunnel in Pittsburgh is 1.1 miles long. There's a man door every .1 mile and a total of 11 doors. 1.1 miles. I've driven through both,yea it's cool in the winter..but I guess I'm just tunnel jaded
Liberty Tubes ! If you're old enough to remember!
Been through it lots of times; I even remember when they doubled it in the mid-60's.
Yes...Remember how smoky it would get with the diesel trucks.
@@vmdairy Yes; used to drive my dad bananas,
Is it longer than the old sideling hill tunnel?
Yes
No it is not..sideling is 7227 '
what happens if you run out of gas in here?
Some secret person emerges from the little passage ways in the wall and provides gasoline and bids you on your way with a tip of the hat.
Your vehicle shuts off and stops.DaH!
Pray that the people that are driving are paying attention and not driving too fast or in a semi truck or it’ll be a disaster waiting to happen
