About southeast of exit 230, and after passing the access road heading south to Meteor Crater, US 66 curved northeast to cross I-40, then made a gradual curve to the southeast. Shortly afterward, US 66 crossed I-40 a second time, where the westbound Meteor Crater Rest Area sits today. Immediately after crossing I-40, US 66 curved northeast to cross over I-40 a third time along with the Santa Fe Railway, then made a sharp turn to the east, followed by a gradual curve to the southeast. At I-40 exit 239, US 66 took the abandoned roadbed back to I-40 and followed the route of the present-day Interstate. About southeast of exit 239, US 66 left I-40 again onto an abandoned roadbed between the current Interstate and the Santa Fe Railway heading southeast, eventually crossing into Navajo County. Where the I-40 Industrial Spur crosses the railroad, the abandoned roadbed, which carried US 66, tied into "Old West Highway 66", where the highway entered Winslow. At the intersection with current SR 99 (former I-40 Business), US 66 headed southeast into downtown Winslow onto Second Street. Through downtown, US 66 passed the Winslow Visitor Center and Standin' on the Corner Park. At the intersection with Williamson Avenue, where SR 99 turns south with southbound SR 87, US 66 met SR 65 at its northern terminus. From here, SR 65 headed south to its other terminus at the Coconino National Forest boundary, while US 66 continued southeast on present-day northbound SR 87 out of town.
