 The complementary ramps were added much later, with the southbound off ramp being a particularly tight and dangerous turn squeezed within the curve of the southbound on ramp, which was replaced in August 2012.A section of I-93 through Franconia Notch State Park, called the Franconia Notch Parkway, was constructed as a two-lane freeway with a median divider.This was built as a compromise between the state's park department and highway officials.
