Basically when it comes to the Conemaugh River Gap, The trail is mostly through it, the problem is the last 3/4 of a mile from the end of the trail in Franklin Borough PA, from which you can peddle by low volume roads to Johnstown Itself, and the Staple Bend Tunnel at the end of the Trail from Mineral Point. From Mineral point you cross under the Main line of the old Pennsylvania Railroad (Now Norfolk and Southern) to the old right of way for the Southern Cambria Railway (A Inter-urban Electric Railway built in 1905 and closed in 1926). Look elsewhere on this forum for pictures of it by me.
From Franklin Borough The trail is quite nice, along the Mountain side for the valley is reserved for the railroad and the Little Conemaugh River:
Looking down the Valley, toward Johnstown, you see the bike trail to your left, in the valley floor you see the Mainline of the Old Pennsylvania Railroad, clearly to the Right. You have a lot of trees in your way to see what is to the Main line left, but to its left you see the Little Conemaugh River and then the Rail-lines for the "Conemaugh and Blacklick railroad" more often called the Blacklick. The Conemaugh and Blacklick do NOT go through the entire gap. The Blacklick tracks stop just pass the Staple bend tunnel. The Blacklick store cars built by the Car Shop (Freight cars for the railroads) on those tracks before such cars are shipped out of town.
At the end of the present trail from Franklin Borough you have three choices, first is down hill to the road along the tracks for the Conemaugh and Blacklick railroad (See below by the trial going downhill). The second choice is to go straight along an old water pipeline. The third is to climb uphill, to over twice as high as the middle trail and take some old logging roads.
Each option has its problems. The lower trail is the easiest to use right now, but the Blacklick Railroad has dump large piles of Dirt to prevent dirt bikers from getting on their property. I do NOT see them agreeing to the move but it is the easiest to build.
Pictures of the Dirt Mounds:
The Middle trial is the least developed, but if built will be the second easiest to bike (The lower trail would be the easiest, but see above about the potential Blacklick Railroad objections).
Looking down from the Middle trial onto the lower trail, and the paved road the lower trail would be on:
Another picture further on the Middle trail of the lower trail:
Even after a hard winter you have a lot of brambles on the Middle Trail:
And several streams of water that has to be addressed (i.e. a pipe under the trail be built for the streams to run under the trail not on the trail):
The Upper trail has the best view but is a climb:
The start of the Upper Trail:
Where the Upper trail goes downhill, another road continues up the Mountain:
As you near the Stable bend Tunnel, the Middle and Upper trails merge together:
Picture of Lower trail from where the Upper and middle trail meet:
Looking to Johnstown from the same point, you see the lower trail to your right, the other trails are to your front (And over grown).
The target of all three trails, the base of Incline #1 that when the Old Portage railway was in use (1830s-1854) Looking up to the Stable Bend tunnel, where the Incline stopped and the cars were transferred to a Steam Locomotive to take them to Incline #2 about 3-4 miles ahead.
Some of the old Survey Markers from about 2000, when the Middle route was first proposed, but still not built:
Please the dates on the Pictures are the Dates I took the pictures EXCEPT the one marked 1/1, those were taken last week, but I had forgotten to reset the clock on my Camera so the bad date.
