Between Lexington in the Shenandoah Valley and Richmond, I-64 uses a lower elevation crossing of the Blue Ridge Mountains located about further north, where it runs parallel to U.S. Route 250 through Rockfish Gap. In contrast, through this section, the older US 60 is mostly a rural two-lane road. With the crossing of the Blue Ridge Mountains at a higher altitude in more rugged terrain, US 60 in this area offers much more challenging and weather-sensitive driving conditions, as well as a history of many crashes in the years before I-64 was completed.
