Interstate 35 in Oklahoma - Route Description

Route Description

Interstate 35 enters Oklahoma with U.S. Highway 77 on a bridge over the Red River in Love County, south of Thackerville. US-77 splits off at Exit 1, but parallels the interstate for its entire length in Oklahoma. I-35 maintains a near-due north–south course through Love and Carter Cos. I-35 provides four exits to Ardmore. After leaving Ardmore, it has a brief concurrency with State Highway 53 and enters Murray County and the Arbuckle Mountains. I-35 then passes through Garvin County and the county seat of Pauls Valley. North of exit 79, I-35 enters McClain County. There, it passes through Purcell and Goldsby.

State Highway 9 joins the interstate crossing over the South Canadian River into Cleveland County, after which it splits off again. It then serves as a major urban interstate in Norman and Moore. Between Norman and Moore, US-77 joins the interstate again. It then enters Oklahoma City and Oklahoma County near milepost 120. Near downtown, I-35 splits off the mainline (which becomes Interstate 235/US-77) and runs concurrent with Interstate 40 for a mile before splitting off to the north again. Interstate 44 then joins I-35 between mileposts 133 and 137. In Edmond US-77 joins the interstate yet again.

At milepost 146, I-35 enters Logan County. It serves Guthrie at Exit 153, where US-77 splits off, and at Exit 157. The interstate then crosses the Cimarron River into Payne County and enters Noble County shortly thereafter. It provides two exits to Perry and serves as the western terminus of the Cimarron Turnpike. After providing access to Tonkawa and Blackwell in Kay County, it crosses into Kansas, becoming the Kansas Turnpike.
