U.S. Route 266
U.S. Route 266 is a, east–west U.S. Numbered Highway in Okmulgee, McIntosh, and Muskogee counties in Oklahoma, United States, that connects U.S. Route 62 and U.S. Route 75 in Henryetta with U.S. Route 64 in Warner. The highway no longer meets the former route of its parent, U.S. Route 66, and is closely paralleled by Interstate 40, which replaced US 266 as the major east–west highway east of Oklahoma City during the 1960s.
Route description
US 266 begins at US 62/US 75 on the northeast side of Henryetta, approximately north of I-40. The highway heads east from this point, quickly crossing into the town of Dewar, which it bisects. As it leaves Dewar, US 266 turns northeast, crossing Coal Creek and the Deep Fork River. The highway bypasses Hoffman to the east, providing access via Hoffman Road. The route then passes through the southeastern outskirts of Grayson. The highway then turns due east. Immediately after the curve, the highway serves as the southern terminus of Oklahoma State Highway 52's northern section. US 266 then continues east into McIntosh County.US 266 continues due east, running parallel to the Deep Fork Arm of Eufaula Lake, the reservoir's northernmost arm. South of Council Hill, the highway intersects Oklahoma State Highway 72 at its southern terminus. US 266 turns south-southeast, continuing the alignment of SH-72. The route then turns back to the east and heads into the city of Checotah. On the west side of town, US 266 has an interchange with the modern freeway route of U.S. Route 69. Further east, in downtown Checotah, the route intersects the old alignment of US 69. The highway heads due east out of Checotah, descending a ridge and passing just south of its summit, Mt. Nebo. The highway passes under I-40 just before crossing into Muskogee County.
Just under east of the McIntosh–Muskogee county line, US 266 intersects the southern Oklahoma State Highway 2. US 266 begins a concurrency with the state route, traveling northwest to an interchange with I-40, numbered as Exit 278. The highways then curve around to due north to pass through Warner. On the north edge of Warner lies an intersection with US 64, where both US 266 and SH-2 end. Continuing straight puts the traveler on westbound US 64 toward Tulsa, while turning right brings the motorist onto eastbound US 64 toward Fort Smith, Arkansas.
