Okla. Stat. tit. 69, § 69-689: Local road design standards - Plans, surveys and

engineering services.

A. The Department of Transportation is hereby directed, in

cooperation with the Oklahoma Cooperative Circuit Engineering

Districts Board, to cause to be developed appropriate local road

design standards for use in constructing projects pursuant to this

program. The standards, upon their adoption by the Transportation

Commission and by those counties wishing to participate in this

program, shall be used for the design and construction of all

projects funded pursuant to this program. However, when funds

available pursuant to this program are used to match federal funds,

projects shall meet appropriate minimum design standards for local

roads and other applicable federal requirements. All plans and

specifications for federal-aid projects shall be subject to the

approval of the Department. To every extent possible, negotiations

with the Federal Highway Administration should be undertaken to

allow application of the County Roads Design Guidelines Manual.

B. Plans, surveys, and engineering shall be the responsibility

of the county in which the project is located. Only registered

professional engineers, approved by the Department of

Transportation, experienced in the design and construction of

highway and related facilities, shall be used for such services.

C. Prior to award of the contract by the Transportation

Commission, the county shall be given the option of accepting or

rejecting the bid submitted by the successful bidder.
