Okla. Stat. tit. 69, § 69-501: Classes of highways - Construction, repair, and

maintenance - Removal from System - Maps.

A. The highway system of this state shall be divided into two

classes to be known as the State Highway System and county highway

system. The State Highway System shall be designated by the

Commission and shall be composed of intercounty and interstate

highways.

B. When the Commission shall have taken over any highway, or

part thereof, as a state highway, the Commission shall become

responsible for the construction, repair and maintenance of such

highway and for this purpose shall be authorized to use any state

highway funds, together with any money derived from any agreement

entered into between the Commission and the federal government, any

county, or any citizen or group of citizens who have made donations

for that purpose.

C. When any segment of the State Highway System is removed from

the system, all right, title, and interest to the road, right-of-

way, and any signs or facilities shall revert to the appropriate

county or municipal authority. The Department of Transportation

shall determine the specific right-of-way to be conveyed and prepare

and execute a conveyance of title document which shall be forwarded

to the local authority to be filed with the county clerk.

D. Prior to returning a state highway back to the county

highway system, the Oklahoma Department of Transportation shall make

any necessary improvements to the road to meet the minimum design

guidelines as set forth in the current State of Oklahoma County Road

Design Guidelines Manual, and provide a driving surface that has no

less than a good rating according to the current County Road Surface

Management System. Prior to returning a state highway bridge back

to the County Bridge System, the Oklahoma Department of

Transportation shall make any necessary improvements to the bridge

so that it will achieve a minimum H-20 twenty (20) ton computed

operating rating according to the National Bridge Inventory System

and a Minimum Scour Rating of 3, NBI Item 113.

E. The Commission shall provide and maintain a map of the state

which shall show all the highways which have been designated as part

of the State Highway System and, when practical, status of

improvement thereon. In addition, the Commission shall include on

such map the principal access road to every city and town not served

by the State Highway System and which has a United States Post

Office or with a population in excess of one hundred (100) persons

according to the latest Federal Decennial Census.
