Interstate 335 Oklahoma

Interstate 335 Oklahoma


Interstate 335 is the planned designation for the Kickapoo Turnpike in the Oklahoma City area. The toll road connects IH 40/U.S. 270-SH 3 in southeastern Oklahoma City with IH 44 (Turner Turnpike) in the town of Luther.

The Kickapoo Turnpike utilizes all electronic toll collection (AET). Four interchanges along the 18.50 mile long route serve rural areas of eastern Oklahoma City, and the growing suburban cities of Choctaw and Harrah.

The toll road commences north from a two lane access road originating at the intersection of SE 89th Street and McDonald Road. Referencing long term plans to extend the turnpike southward, exit numbers increase from 130 at the exchange with IH 40.

The proposed Oklahoma City Outer Loop is part of the Oklahoma Turnpike Authority (OTA) 15 year, $5 billion program Access Oklahoma program launched in February 2022. The East-West Connector section of the OKC Outer Loop extends 28 miles southwest from IH 40 at the Kickapoo Turnpike to IH 44 at the Tri-City area of Newcastle, Blanchard and Tuttle. Cost projections as of March 25, 2022 were $1.5 billion for the East-West Connector.

The South Extension Turnpike branches south from the OKC Outer Loop 19 miles to IH 35, just east of SH 74 near Purcell. The toll is projected to travel west of Lake Thunderbird from near Franklin in the city of Norman to SH 9. Ideally Interstate 335 will follow the eastern section of the OKC Outer Loop and the South Extension Turnpike.

The proposed Interstate Designations approved by the Oklahoma Transportation Commission in September 2022

Designating Interstate 335 along the Kickapoo Turnpike was approved by the Oklahoma Transportation Commission during the September 11, 2023 meeting. Agenda Item Number 131, State Highway System Numbering Revision defined IH 335 as follows:

Addition of the I-335 Designation to the State Highway System, a 18.71 mile stretch of roadway, known as the Kickapoo Turnpike, beginning at the intersection of Kickapoo Turnpike and I-44\Turner Turnpike and going south to the intersection of the Kickapoo Turnpike and I-40.

The revision requires approval from the American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration. AASHTO subsequently approved the Oklahoma Department of Transportation (ODOT) application for the establishment of I-335 at the Fall 2023 meeting.
