New Hampshire Route 112

New Hampshire Route 112 (abbreviated NH 112) is a 56.39-mile (90.75 km) long east–west state highway in northern New Hampshire. The highway winds across the state, connecting Bath to Conway via the scenic and mountainous area of the White Mountain National Forest. Part of this highway, which runs through the White Mountains, is known as the Kancamagus Highway. This highway is known for its views of autumn foliage and is a popular drive in September and October for so-called leaf peeping tourism.

The Kancamagus Highway is a 26.5-mile (42.6 km)-long two-lane road that runs east and west through the White Mountains and constitutes the eastern half of New Hampshire Route 112. It has been designated a National Scenic Byway by the United States Department of Transportation under the name Kancamagus Scenic Byway.

The highway stays open all winter, although it occasionally closes for short periods while crews clear heavy snows. Its only major intersection, Bear Notch Road, which connects with the town of Bartlett, is closed all winter.

Following Hurricane Irene in August 2011, two sections of Route 112 were closed, pending repair work and evaluation of damage. The Kancamagus Highway was closed from the Sabbaday Falls picnic area across Kancamagus Pass to the Discovery Trail parking area in the eastern part of Lincoln. A section of the western portion of Route 112 along the Wild Ammonoosuc River was closed; as of September 6, 2011, a single lane of the western section had been reopened. As of late June 2012, the highway had been completely reopened, though some stretches were in the process of being repaved.
