apply to obligations--
        (1) under section 125 of title 23, United States Code;
        (2) under section 147 of the Surface Transportation Assistance 
    Act of 1978;
        (3) under section 9 of the Federal-Aid Highway Act of 1981;

    $639,000,000 per fiscal year.
    (c) Distribution of Obligation Authority.--For each of fiscal years 
1998 through 2003, the Secretary shall--
        (1) not distribute obligation authority provided by subsection 
    (a) for such fiscal year for amounts authorized for administrative 
    expenses and programs funded from the administrative takedown

        forth in paragraphs (1) through (7) of subsection (b) and sums 
        authorized to be appropriated for section 105 of title 23,

    multiplying the ratio determined under paragraph (3) by the sums 
    authorized to be appropriated for such section (except in the case 
    of section 105, $2,000,000,000) for such fiscal year;
        (5) distribute the obligation authority provided by subsection

    and (2) and amounts distributed under paragraph (4) for each of the 
    programs that are allocated by the Secretary under this Act and 
    title 23, United States Code (other than activities to which 
    paragraph (1) applies and programs to which paragraph (4) applies)

    authorized to be appropriated for such program for such fiscal 
    year; and
        (6) distribute the obligation authority provided by subsection 
    (a) less the aggregate amounts not distributed under paragraphs (1) 
    and (2) and amounts distributed under paragraphs (4) and (5) for

    than the minimum guarantee program, but only to the extent that 
    amounts apportioned for the minimum guarantee program for such 
    fiscal year exceed $2,639,000,000, and the Appalachian development 
    highway system program) that are apportioned by the Secretary under 
    this Act and title 23, United States Code, in the ratio that--
            (A) sums authorized to be appropriated for such programs 
        that are apportioned to each State for such fiscal year, bear 
        to
            (B) the total of the sums authorized to be appropriated for 
        such programs that are apportioned to all States for such 
        fiscal year.
    (d) Redistribution of Unused Obligation Authority.--Notwithstanding 
subsection (c), the Secretary shall after August 1 of each of fiscal 
years 1998 through 2003 revise a distribution of the obligation 
authority made available under subsection (c) if a State will not 
obligate the amount distributed during that fiscal year and 
redistribute sufficient amounts to those States able to obligate 
amounts in addition to those previously distributed during that fiscal 
year giving priority to those States having large unobligated balances 
of funds apportioned under sections 104 and 144 of title 23, United 
States Code, under section 160 of title 23, United States Code (as in 
effect on the day before the date of enactment of this Act), and under 
section 1015 of the Intermodal Surface Transportation Act of 1991 (105 
Stat. 1943-1945).
    (e) Applicability of Obligation Limitations to Transportation 
Research Programs.--Obligation limitations imposed by subsection (a) 
shall apply to transportation research programs carried out under 
chapter 3 of title 23, United States Code, and under title VI of this 
Act.
    (f) Redistribution of Certain Authorized Funds.--Not later than 30 
days after the date of the distribution of obligation authority under 
subsection (c) for each of fiscal years 1998 through 2003, the 
Secretary shall distribute to the States any funds (1) that are 
authorized to be appropriated for such fiscal year for Federal-aid 
highway programs (other than the program under section 160 of title 23, 
United States Code) and for carrying out subchapter I of chapter 311 of 
title 49, United States Code, and chapter 4 of title 23, United States 
Code, and (2) that the Secretary determines will not be allocated to 
the States, and will not be available for obligation, in such fiscal 
year due to the imposition of any obligation limitation for such fiscal 
year. Such distribution to the States shall be made in the same ratio 
as the distribution of obligation authority under subsection (c)(6). 
The funds so distributed shall be available for any purposes described 
in section 133(b) of title 23, United States Code.
    (g) Special Rule.--Obligation authority distributed for a fiscal 
year under subsection (c)(4) for a section set forth in subsection 
(c)(4) shall remain available until used for obligation of funds for 
such section and shall be in addition to the amount of any limitation 
imposed on obligations for Federal-aid highway and highway safety 
construction programs for future fiscal years.
    (h) Increase in Obligation Limit.--Limitations on obligations 
imposed by subsection (a) for a fiscal year shall be increased by an 
amount equal to the amount determined pursuant to section 
251(b)(1)(B)(ii)(I)(cc) of the Balanced Budget and Emergency Deficit 
Control Act of 1985 (2 U.S.C. 901(b)(2)(B)(ii)(I)(cc)) for such fiscal 
year. Any such increase shall be distributed in accordance with this 
section.
    (i) Limitations on Obligations for Administrative Expenses.--
Notwithstanding any other provision of law, the total amount of all 
obligations under section 104(a) of title 23, United States Code, shall 
not exceed--
        (1) $320,000,000 for fiscal year 1998;
        (2) $350,000,000 for fiscal year 1999;
        (3) $370,000,000 for fiscal year 2000;
        (4) $390,000,000 for fiscal year 2001;
        (5) $410,000,000 for fiscal year 2002; and
        (6) $430,000,000 for fiscal year 2003.

            Alaska and Puerto Rico shall be designed in accordance with 
            such geometric and construction standards as are adequate 
            for current and probable future traffic demands and the 
            needs of the locality of the highway.
            ``(C) Location.--Highways on the Interstate System shall be 
        located so as--
                ``(i) to connect by routes, as direct as practicable, 
            the principal metropolitan areas, cities, and industrial

        practicable, each route of the Interstate System shall be 
        selected by joint action of the State transportation

            a highway on the Interstate System, the Secretary may, upon

            construction standards for the Interstate System and has 
            been designated as a route on the Interstate System.
