SEC. 113. TOLL ROADS, BRIDGES, AND TUNNELS. (a) Approval as Part of Interstate System.—Upon a finding by the Secretary of Commerce that such action will promote the development of an integrated Interstate System, the Secretary is authorized to approve as part of the Interstate System any toll road, bridge, or tunnel, now or hereafter constructed which meets the standards adopted for the improvement of projects located on the Interstate System, whenever such toll road, bridge, or tunnel is located on a route heretofore or hereafter designated as a part of the Interstate System: Provided, That no Federal-aid highway funds shall be expended for the construction, reconstruction, or improvement of any such toll road except to the extent hereafter permitted by law: Provided further, That no Federal-aid highway funds shall be expended for the construction, reconstruction, or improvement of any such toll bridge or tunnel except to the extent now or hereafter permitted by law. (b) Approaches Having Other Use.—The funds authorized under this title, or under prior Acts, shall be available for expenditure on projects approaching any toll road, bridge, or tunnel to a point where such project will have some use irrespective of its use for such toll road, bridge, or tunnel. (c) Approaches Having No Other Use.—The funds authorized under section 108 (b) of this title, or under prior Acts, shall be available for expenditure on Interstate System projects approaching any toll road on the Interstate System, even though the project has no use other than as an approach to such toll road: Provided, That agreement satisfactory to the Secretary of Commerce has been reached with the State prior to approval of any such project (1) that the section of toll road will become free to the public upon the collection of tolls sufficient to liquidate the cost of the toll road or any bonds outstanding at the time constituting a valid lien against said section of toll road covered in the agreement and their maintenance and operation and debt service during the period of toll collections and (2) that there is one or more reasonably satisfactory alternate tree routes available to traffic by which the toll section of the System may be bypassed. (d) Effect on Certain Prior Acts.—Nothing in this title shall be deemed to repeal the Act approved March 3, 1927 (44 Stat. 1398), or subsection (g) of section 204 of the National Industrial Recovery Act (48 Stat. 200), and such Acts are hereby amended to include tunnels as well as bridges.
