Franconia Notch (elev. 1,950 feet/590 m) is a major mountain pass through the White Mountains of New Hampshire. Dominated by Cannon Mountain to the west and Mount Lafayette to the east, it lies principally within Franconia Notch State Park and is traversed by the Franconia Notch Parkway (Interstate 93 and U.S. Route 3). The parkway required a special act of Congress to sidestep design standards for the Interstate highway system because it is only one lane in each direction.
