US 270 serves most of the towns anchoring the area east of Oklahoma City, including Shawnee, Tecumseh, Seminole, Wewoka, and Holdenville. It continues southeast to the city of McAlester, a major southeastern Oklahoma city. It also serves many of the small towns east of McAlester, such as Krebs, Alderson, Bache, Haileyville, and Hartshorne. After passing through Hartshorne, the roads curves to the northeast before turning onto a due east course taking it through Wilburton, Red Oak, and Wister. In Wister, it turns south, running across Wister Lake's dam, and proceeding southeast to Heavener. There, it meets US 59, which it will follow for the rest of its time in Oklahoma. The town highways head south from Heavener, passing through the Wister Wildlife Management Area before entering the Ouachita National Forest. The route serves as the northern terminus of US 259 near Page. The road then squeezes into a valley between Black Fork Mountain and Rich Mountain. In this valley, it crosses the state line into Arkansas. Arkansas US 270 enters Arkansas with US 59, and runs east to Acorn, where it meets US 71. The route then travels 15 miles north on US 71 to Y City where it splits off and continues east. The route then meets AR 88 in Pencil Bluff and AR 27 in Mt. Ida before heading to Hot Springs. Entering the city, US 270 meets US 70 southwest of town and runs concurrent with it around Hot Springs using the Dr. Martin Luther King Jr. Expressway before leaving the freeway and running along Malvern Avenue southeast of the city. US 270 intersects with I-30 just outside Malvern, running a short distance northeast on the freeway before interchanging with the George Hopkins Loop bypass and running south around the city. After meeting with US 67 east of town, the alignment then turns east-southeast meeting AR 229 in Poyen and AR 190/AR 291 in Prattsville before crossing paths with US 167 in Sheridan.
