i think that trail is a long way from being completed. I've seen where the trail could connect to the montour two different ways. one would be the chartiers creek greenway which will connect to the panhandle trail you can find information about it here:

the other would be a direct connection called The Ohio Riverfront Montour Connection. That "trail" was out for bid on the feasibility study. I don't know if the feasibility study was awarded to any one yet. The latest information i could find is here:
