Just southeast of Parks, where Old Route 66 dead ends, US 66/US 89 crossed present-day I-40 diagonally to briefly parallel the Santa Fe Railway, before being subsumed into the route of I-40 once again. The old highway left I-40 again briefly along an abandoned graded curve on the south side of the Interstate just west of the Parks Rest Area. East of the rest area, US 66/US 89 split off a third time onto Bellemont Camp Road. The highway continued diagonally southeast through Bellemont, then merged back into I-40. The eastern end of Bellemont Camp Road (which can not be used as a through route by travelers today) is still paved in original concrete. Heading southeast out of Bellemont, US 66/US 89 used the route of I-40 until reaching present-day exit 191. Here, the highway angled southeasterly on I-40 Business into Flagstaff.
