NH 18 closely parallels I-93 for its entire length and has several interchanges with the Interstate highway.

Route description

NH 18 begins as a spur of I-93 at the height of land in Franconia Notch. NH 18 proceeds to the northwest, intersecting NH 141 and NH 142, near its interchange with I-93. In downtown Franconia, NH 18 joins with NH 116 and meets the eastern end of NH 117 before leaving town and crossing into Bethlehem. NH 18 has two interchanges with I-93 in Bethlehem, joining U.S. Route 302 westbound at the second one. The highway crosses into Littleton, splitting with NH 116 in the center of town. Just west of downtown, US 302 splits from NH 18 as well. Northwest of town, NH 18 joins NH 135 near another interchange with I-93. The two routes have a direct interchange with I-93 near the Connecticut River at exit 44. NH 135 splits off NH 18 before it crosses the river into Vermont and becomes VT 18.
