Petrified Forest stretches between Interstate 40 and U.S. 180. Visitors traveling west on Interstate 40 should exit at milepost # 311, drive through the park and connect with U.S. 180 at the south end. Visitors can then take U.S. 180 west to Holbrook and continue west on Interstate 40. East-bound visitors can exit Interstate 40 at Holbrook and take U.S. 180 east to the park, drive north through the park, and return to Interstate 40.
