U.S. Route 266

, May 2006 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. US 266 begins a concurrency with the state route (SH-2), 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. ==History==

Prior to the inception of the U.S. highway system, Oklahoma State Highway 9 (SH-9) covered much of the corridor from Oklahoma City to Spiro. Upon the US route system's inception, US 266 replaced SH-9 from its junction with US 66 at 23rd Street and Lincoln Boulevard in Oklahoma City to US 64 in Warner. By 1930, along with changes to several other branches of US 66, the route was truncated at Henryetta. The segment from Oklahoma City to Henryetta became part of US 62, which was commissioned in 1930. ==Junction list==
