Okla. Stat. tit. 69 § 2003
In order to maximize the funds available for the construction, improvement, and maintenance of the highway and bridge projects set forth in Section 2002 of Title 69 of the Oklahoma Statutes, the Oklahoma Department of Transportation may utilize funds dedicated to a highway or bridge project to obtain additional federal matching funds for any bridge project for which such federal matching funds are available. If federal matching funds are available for the construction of all or part of a bridge project, the Department of Transportation may give priority to the construction of all or part of the bridge project, despite any description of such project to the contrary, in order to obtain the federal matching funds. Any remaining funds for such project may be used for the purchase of right-of-way and relocation expenses.
