The story
The 14-mile Needles Highway (SD-87), from US-16A to Sylvan Lake, was surveyed on foot and horseback by former governor Peter Norbeck, who wanted it to showcase the park's wind-and-frost-carved granite pinnacles. Construction finished in 1922. The route is named for the "needles" — slender spires — that line it, the most famous being the Needle's Eye. Its single-lane Needles Eye Tunnel, blasted through solid granite, is just 8 feet wide and about 9 feet 9 inches high, too tight for many RVs.

Governor Peter Norbeck personally walked and rode horseback over every foot of the route before a single machine touched it, deliberately routing the Needles Highway through the most dramatic granite spires in the Black Hills instead of the shortest path.
