Okla. Stat. tit. 69, § 69-660: Replacement, expansion, or repair of bridges -

Expenditures.

The boards of county commissioners may enter into cooperative

agreements with the Oklahoma Turnpike Authority for the purpose of

replacement, expansion or repair of functionally obsolete and

structurally deficient bridges which cross over or under turnpikes.

The expenditures for such projects will be from any federal, state

or county public funds appropriated and earmarked for such purpose.

Counties may apply for the expenditure of these earmarked funds for

projects that have been requested by the board of county

commissioners of the county where the bridge is located. Once

approved by the Oklahoma Cooperative Circuit Engineering Districts

Board, the Board will select and prioritize the bridge replacement

projects based on criteria which shall include, but not be limited

to, high traffic volume and current bridge safety assessments.
