“Explore America's only abandoned superhighway turned multi-use trail.”— Jeff Menaker
From the east side, it is a short run to the larger of the two tunnels: Sideling Hill Tunnel. This tunnel is approximately 1.3 miles long with a slight crest in the middle. At approximately 3.5 miles farther on (with some slight rolling hills along the way), runners will come to Ray's Hill Tunnel, which is about 0.5 miles long. The old roadway continues a bit until reaching the western access near US 30.
The trail is entirely on old turnpike roadbed. The pavement is broken in spots, but easily traveled. Inside the tunnels can be extremely dark and damp. Watch for broken concrete, drips from overhead, and trash (including glass) in the tunnels.
