The YouTube link below illustrates the exit out of Pittsburgh's Point State Park, the ride along the Monongahela River, the new switchback bridge up to street level and the path to and across Grant Street in downtown Pittsburgh to continue down the GAP. While it is certainly not professional quality, it does show that route as I rode it recently. Perhaps it will help those looking to do so for the first time. The video can be found at:
