Whenever a proposed interstate bridge is to be acquired, purchased or constructed, any city, county, or other political subdivision located in relation to such facility so as to benefit directly or indirectly thereby, may, either jointly or separately, at the request of the department advance or contribute money, rights-of-way, labor, materials, and other property toward the expense of acquiring, purchasing or constructing the bridge, and for preliminary surveys and the preparation of plans and estimates of cost therefor and other preliminary expenses. Any such city, county, or other political subdivision may, either jointly or separately, at the request of the department advance or contribute money for the purpose of guaranteeing the payment of interest or principal on the bonds issued by the department to finance the bridge. Appropriations for such purposes may be made from any funds available, including county road funds received from or credited by the state, or funds obtained by excess tax levies made pursuant to law or the issuance of general obligation bonds for this purpose. Money or property so advanced or contributed may be immediately transferred or delivered to the department to be used for the purpose for which contribution was made. The department may enter into an agreement with a city, county, or other political subdivision to repay any money or the value of a right-of-way, labor, materials or other property so advanced or contributed. The department may make such repayment to a city, county, or other political subdivision and reimburse the state for any expenditures made by it in connection with the bridge out of tolls and other revenues for the use of the bridge.
