These are the bridges and tunnels headed west on the West Penn Trail through the Conemaugh River Lake Section and touching into the Bow Ridge Section. This is a 1907 rail line that contains a total of five massive cut stone arch bridges, one trestle bridge and two blocked tunnels cut into the Bow Ridge mountain.
This is the first of the bridges starting from the east, a trestle bridge called the Social Hall Bridge, named for the former town of Social Hall.

Livermore was an old canal town established in 1827 by John Livermore who I am assuming was a relative of Alonzo Livermore, Asst. Engineer of the Western Division of the Pennsylvania Canal. The town was dismantled in the 1950's as part of the Army Corp Of Engineers Conemaugh Dam flood control project. Nothing remains of the town today and it is under water when the river is high.
At it's heyday the town contained hotels, numerous businesses and churches, residences and was a stopping point for travelers on the mainline canal. Charles Dickens is reported to have stayed here while traveling on the canal in 1842.
For kids growing up around here Livermore was the stuff of legend and mystery. Many myths surrounded the town and it was often a rite of passage to visit at night long before this trail was open. It was rumored that the town was pretty much flooded over night, none of the towns people had an opportunity to escape and the buildings were left intact. It turns out that none of that is true but coming back here late at night, crossing the tracks and coming to the gate left a lot to the imagination and was pretty eerie. I loved every second of it! Many kids walked down to the bridge only to turn around and go running back to the car.
Livermore Cemetery sits on top of the hill and another rumor was Night Of The Living Dead was filmed there but it wasn't. It was filmed in Evans City several miles northwest of here.
Livermore Bridge is the second of the massive stone arch bridges.
This is an early map of Livermore:

|This is part of the bridge that led out of Livermore to the town of Filmore across the river. Filmore was a smaller town but shared the same fate as Livermore.|

I have more photos of Livermore Bridge in an earlier post on this blog.
Now on to the third stone bridge.
|This is the second bridge before the dam. The bridges are all the same height. Notice how the water level keeps rising as we get closer to the dam.|
|These are old bridge supports from the 1854 rail line.|
|Notice that the closer we get to dam, the more submerged the bridges get.|

Now onto the final bridge before the dam.
|Heavily flooded. |
There are a total of three tunnels that go through Bow Ridge. The first tunnel was built in the 1820's and served the mainline canal. Today, that tunnel is deep under water but it has the distinction of being the third tunnel ever built in America. The second tunnel was from the 1854 rail line and the third was from the 1907 line. All of these tunnels have been plugged in the middle with 20 feet of concrete to prevent water flooding through them and bypassing the dam.
|This is all that remains of the eastern portal of the 1854 rail line tunnel. This tunnel was built in 1864 and it wasn't until 1871 that the railroad reached Saltsburg. It is almost completely swallowed up by the hillside.|
|A.C. Shand designed this tunnel too.|

At this point in the trail you have to climb a set of stairs on the side of the mountain and ride/hike to the other side.

|The last, and in my opinion the most impressive of the stone arch bridges. Notice the curve of this enormous bridge.|
