US-69 then crosses into Pittsburg County. US-69 runs just east of Kiowa, where it intersects State Highway 63 at its western terminus. US-69 runs along the east edge of the McAlester Army Ammunition Plant, which it provides access to via an interchange near Savanna. It then has an interchange with the Indian Nation Turnpike, after which it enters McAlester. US-69 mostly runs along the east side of McAlester, the county seat of Pittsburg County, with the downtown area being served by U.S. Highway 69 Business. The main route of US-69 has an interchange with US-270/SH-1/SH-31. North of McAlester, US-69 reunites with its business loop at an interchange which also serves as the southern terminus of SH-113. US-69 regains freeway status at this interchange, and begins crossing over several arms of Lake Eufaula. US-69 provides several interchanges for lake access. Other interchanges serve the northern terminus of SH-113 (which has both termini at US-69) and the western terminus of SH-9A. US-69 then crosses the main channel of the Canadian River into McIntosh County.
