Paw Paw tunnel[edit]
Main article: Paw Paw Tunnel
One of the most impressive engineering features of the canal is the Paw Paw Tunnel, which runs for 3,118 feet (950 m) under a mountain.[56] Built to save six miles (10 km) of construction around the obstacle, the 3/4-mile tunnel used over six million bricks. The tunnel took almost twelve years to build; in the end, the tunnel was only wide enough for single lane traffic.[116] One notorious incident included two captains who refused to budge for several days. The company official threw green cornstalks onto a roaring fire at the upwind portion of the tunnel, smoking the offenders out.[49]
