Where I-40 curves southeast, US 66 continued northeast onto Hibbard Road, then made a sharp turn east onto an old roadbed from the Interstate. US 66 proceeded to make a gradual S-curve to the southeast and cross a tributary of the Little Colorado River on another no longer extant bridge. The highway continued straight southeast from the bridge crossing for , then made a sweeping curve south by southeast and crossed I-40. On the south side of I-40, US 66 made another gradual curve back to the southeast, then a second curve to the east, and merged back into Hibbard Road. Where Hibbard Road ends, US 66 continued diagonally across I-40, then turned immediately south again, crossing I-40 a second time onto the south frontage road. Here, US 66 arrived at the Jack Rabbit Trading Post. The trading post once posted signs up and down the highway for hundreds of miles between Arizona and Missouri. Today, one of the iconic billboards still stands next to the trading post. It is a wooden sign displaying a black jackrabbit on a yellow background with the phrase "Here It Is" spelled in large capitalized red letters on the left side of the jackrabbit. US 66 continued southeast from the trading post along the south frontage road, paralleling the Santa Fe Railway and Little Colorado River. At the point where the south frontage road curves northeast to straddle the south side of I-40, US 66 crossed the Interstate becoming Main Street into Joseph City. US 66 through Joseph City is designated today as I-40 Business. East of town, US 66 curved southeast across I-40 onto the south frontage road close to the town post office. Where the frontage road makes a quick U-shape near exit 247, US 66 continued straight. In front of the Cholla Power Plant, US 66 curved to rejoin I-40. US 66 followed I-40 southeast past a reservoir and earthen dam. Where I-40 curves to the east, US 66 split off to the north side of I-40, becoming the north side frontage road. US 66 followed the north frontage road for a short distance, then rejoined I-40 momentarily at exit 283. Immediately after rejoining the Interstate, US 66 diverged, turning to the northeast, and rejoined the north frontage road. Where the frontage road makes a sharp curve to the north, US 66 continued straight east on an abandoned roadbed to I-40
