Interstate 35 (I-35), in the US State of Oklahoma, runs from the Red River at the Texas border to the Kansas state line near Braman for a length of 236 miles (380 km).^[1] I-35 has one auxiliary route in the state, I-235, in the inner city of Oklahoma City. A second auxiliary route, I-335, is planned as the designation for the Kickapoo Turnpike, although it will not meet I-35 until the southern extension of the turnpike to a junction with I-35 in Purcell is built. Excluding the Panhandle, I-35 forms the informal bisector for central Oklahoma, and along with US 81/US 283 in western Oklahoma and US 69/US 75 in the eastern portion, it provides one of the main north-south corridors through the state.
