Okla. Stat. tit. 69, § 69-661: Priority of replacement or reconstruction projects -

Selection - Apportionment of funds.

A. When a county receives monies pursuant to the County Bridge

and Road Improvement Act, a county shall give priority to

reconstructing, replacing, or closing those bridges in the county

that are rated less than three (3) tons or fifteen (15) tons or less

for those bridges on school bus routes. Bridge and road replacement

or reconstruction projects shall be selected by the individual

boards of county commissioners and shall be based on a countywide

assessment of bridge and road reconstruction and replacement needs.

B. Funds accruing to the County Bridge and Road Improvement

Revolving Fund shall be apportioned on the basis of a formula

developed by the Department of Transportation and approved by the

Department of Transportation County Advisory Board created pursuant

to Section 302.1 of this title. The formula shall be similar to

that previously used for the distribution of County Bridge

Improvement Program funds, but shall also take into consideration

the effects of terrain and traffic volume as related to county road

improvement and maintenance costs.
