Okla. Stat. tit. 69, § 69-3017

Until all bonds and the interest thereon are paid in full upon

any toll expressway project undertaken by any trust under the

provisions of this act, the Oklahoma Tax Commission shall each month

determine an amount equal to the motor fuel excise taxes computed on

ninety-seven and one-half percent (97 1/2%) of the total gallonage

of all fuels consumed on such toll expressway, during the calendar

month in which the tax being apportioned accrued, and apportion a

sum equal to such amount from all gasoline tax collections as

follows: Ninety-seven percent (97%) of such amount to such trust

and three percent (3%) to the General Revenue Fund of the State

Treasury. Provided, however, that the apportionments herein remitted

shall apply only to such trust that issues bonds in connection with

the construction of a toll expressway project beginning in or near

the City of Tulsa and the Port of Catoosa and extending in a

northwesterly direction to a point in or near Ponca City, or at a

point on the Kansas-Oklahoma state boundary line, which said toll

expressway shall be called "Northwest Passage", or to a turnpike or

any parts thereof beginning in the vicinity of the City of Davis and

extending in a northeasterly direction, by way of the vicinity of

the City of Ada, to a connection in the vicinity of Henryetta or in

the vicinity of the intersection of State Highway 48 and Interstate
