the highway begins a concurrency with SH-33. SH-33 and SH-66 will remain signed together as they enter the Tulsa metropolitan area. Tulsa area SH-33/66 next enter Sapulpa, the county seat of Creek County and a suburb of Tulsa. In Sapulpa, the two highways serve as the western terminus of SH-117. They then come to the intersection of Dewey Avenue and Main Street in downtown Sapulpa, where SH-33 ends. This intersection also serves as the southern terminus of SH-97. SH-66 continues east through the intersection, joined by US-75 ALT. The two highways intersect SH-117A at its northern terminus, and turn left to continue its alignment. US-75 ALT/SH-66 parallel the Turner Turnpike within sight distance for the remainder of their journey in Creek County. Near the Creek–Tulsa County line, the Turner Turnpike ends, and SH-66 merges onto the now toll-free I-44. US-75 ALT ends at the merge. I-44/SH-66 cut diagonally through the city of Tulsa. In West Tulsa, Interstate 244 branches off to serve the downtown area. I-44/SH-66 follow the Skelly Drive through midtown. The highways interchange with the Okmulgee Beeline, the US-75 freeway before crossing the Arkansas River. The next freeway interchange is with the Broken Arrow Expressway, carrying US-64 and SH-51, followed by the Mingo Valley Expressway, carrying US-169 I-244 then merges with I-44 at its eastern terminus. I-44/SH-66 cross into Rogers County and the suburb of Catoosa, serving as the southern terminus of SH-167. SH-66 then splits off from I-44, initially following an old alignment of the Interstate where it transitioned into the Will Rogers Turnpike. SH-66 then downgrades to an expressway as it passes through Catoosa, home of the Blue Whale. Northeast of Catoosa, near Verdigris, SH-66 intersects SH-266 at its eastern terminus. Northeast Oklahoma The next town that SH-66 serves after leaving the Tulsa area is Claremore, seat of Rogers County. In Claremore, SH-66 has brief concurrencies with SH-20 and SH-88. The highway continues northeast through Rogers County, bypassing Sequoyah to the west and serving as the western terminus of SH-28A in Foyil. The highway passes through Bushyhead northeast of Foyil, and then intersect SH-28 in Chelsea further northeast. The route then crosses into Craig County, where it serves the unincorporated place of White Oak. The SH-66 designation then comes to an end at US-60, which Route 66 historically followed into Vinita.
