List of Oklahoma numbered highways

Oklahoma has a large network of numbered highways maintained by the state. These roads fall into one of three categories: Interstate highways, U.S. highways, and state highways. Interstate highways and U.S. highways are continuous with surrounding states, while state highways are not (though Oklahoma and another state's department of transportation may coordinate numbering).

The majority of the numbered highways within Oklahoma are maintained by the Oklahoma Department of Transportation. The only exceptions are sections of Interstate 44 and U.S. Highway 412, which run along turnpikes maintained by the Oklahoma Turnpike Authority. (I-44 runs along the H.E. Bailey, Turner, and Will Rogers Turnpikes; US-412 is signed along the Cimarron and Cherokee Turnpikes.)

Individual counties may establish a numbering system to apply to roads that they maintain. These highways are not listed here.

Interstate highways

tate highways

Oklahoma's state highways serve as the second-lowest tier on the Oklahoma road system. They are marked with a number contained inside an outline of the state, having been formerly marked inside a white circle in a black box until January 2006. [http://www.okladot.state.ok.us/public-info/press/06-017_new_state_highway_signs_unveiled.pdf] [http://www.us-highways.com/newok.htm] [http://www.kctv.com/Global/story.asp?S=4340917] The number is generally even if the highway runs north-south, and odd if it runs east-west (this is the opposite of the numbering for Interstate and US Highways), though exceptions abound.

SH-60, SH-62, SH-75, and SH-81 have not been issued for state highways so that they are not confused with US Highways and Interstates bearing the same number designation. SH-35 has been issued, but it is only for a short spur, far from I-35, SH-69 was once assigned but this designation has since been revoked. Other two-digit highways that have yet to be assigned include: SH-12, SH-13, SH-21, SH-41, SH-57, SH-61, SH-68, and SH-90. SH-40 was once issued, but was absorbed into U.S. Highway 177; see SH-40A. SH-41, which was an east-west route across west-central Oklahoma that began at the intersection of S.W. 29th and May Avenue in Oklahoma City and veered southwest to Mustang, Union City and Minco before continuing west through Binger, Eakly, Cordell and Sayre and then crossing the Texas border near Sweetwater, was redesignated as SH-152 over its entire length in 1955. Across the Texas Panhandle, the highway continues as TX-152 to Dumas, Texas.

Many Oklahoma state highways have short spur routes connecting them to towns which lay off of the main route. Many times, these bear the same number as the parent highway, with a letter suffix. Highways with these spurs are marked in the chart below with a ¹. Some state highway spurs and loops from US highways have designations that are drawn from the parent US Highway designation.

As higher-level roads replaced sections of some routes, those sections sometimes had their designation revoked. This led to some highways being fragmented, missing one or more sections in the middle of the road. There are also a few unrelated highways that are designated in completely different parts of the state with the same name.
