Future Interstate 343 Oklahoma

Overview

The Oklahoma Department of Transportation submitted an application to the American Association of State Highway and Transportation Officials (AASHTO) for the establishment of Interstate 343 along the Muscogee Turnpike, between Broken Arrow and Webber Falls, on October 6, 2025. The request was approved by the Route Numbering Committee at the Fall 2025 Meeting in November.

The Muscogee Turnpike joins the Tulsa area with Muscogee and the Interstate 40 corridor. The proposed route for I-343 overlays all 52.32 miles of the toll road.

The Oklahoma Turnpike Authority (OTA) and the Indian Nation Council of Governments (INCOG) previously requested to the Oklahoma Transportation Commission (OTC) for the redesignation of the Muscogee Turnpike as Interstate 343 at the Commission Meeting held on May 5, 2025. Approval was recommended by the OTA (Oklahoma Transportation Commission, 2025, Agenda Item 64).

History

The Muskogee Turnpike was scheduled to open on August 1, 1969. The OTA built the toll road southeast from SH 51 near Broken Arrow to the Muskogee East Industrial Bypass at Hyde Park Road. The turnpike resumed south from Hancock Avenue to Interstate 40 near Webber Falls (Big Basin Herald, 1969a). The Muskogee East Industrial Bypass was constructed by the Oklahoma State Highway Department, and was not ready for traffic by August 1, 1969. The department indicated that two lanes of the bypass would open on August 22, 1969, and until that time, the southern section of the turnpike was inaccessible. As such the OTA committed to opening as much as possible that month (Big Basin Herald, 1969b).

The Muskogee Turnpike finally opened to traffic on October 16, 1969. Construction of the 53.1 mile long toll road was financed by a $32.3 million bond issue (The Oklahoman, 2012). The toll rate was 60 cents at the SH 51 toll plaza to the north and 40 cents at the plaza south of Muskogee. The toll road construction included the Turnpike Concession (service) area at mile marker 25 (Big Basin Herald, 1969a).
