Notes

  • A 340-foot (104 m) deep cut in the top of Sideling Hill was made to allow the highway to pass through six miles (10 km) west of Hancock. This exposed a syncline, a trough-shaped fold in the rock of Sideling Hill. An exhibit center was built at the site, and it opened in 1991. This cut is one of the most impressive rock exposures in the northeastern United States.
  • The section through Cumberland, Maryland is one of the most substandard sections of Interstate highway, falling well below Interstate standards, however, there was no realistic alternate route so it was included in I-68. Built as U.S. Highway 40 in 1965, the tight character, narrow lanes and very limited sight distance warrant a 40 mph (60 km/h) speed limit and most exits are posted at 15 mph (25 km/h).
