§ 120. Federal share payable
(a)
Interstate System Projects.—
(1)
In general.—
Except as otherwise provided in this chapter, the Federal share payable on account of any project on the Interstate System (including a project to add high occupancy vehicle lanes and a project to add auxiliary lanes but excluding a project to add any other lanes) shall be 90 percent of the total cost thereof, plus a percentage of the remaining 10 percent of such cost in any State containing unappropriated and unreserved public lands and nontaxable Indian lands, individual and tribal, exceeding 5 percent of the total area of all lands therein, equal to the percentage that the area of such lands in such State is of its total area; except that such Federal share payable on any project in any State shall not exceed 95 percent of the total cost of such project.
(b)
Other Projects.—
Except as otherwise provided in this title, the Federal share payable on account of any project or activity carried out under this title (other than a project subject to subsection (a)) shall be—
(1)
80 percent of the cost thereof, except that in the case of any State containing nontaxable Indian lands, individual and tribal, and public domain lands (both reserved and unreserved) exclusive of national forests and national parks and monuments, exceeding 5 percent of the total area of all lands therein, the Federal share, for purposes of this chapter, shall be increased by a percentage of the remaining cost equal to the percentage that the area of all such lands in such State, is of its total area; or
(2)
80 percent of the cost thereof, except that in the case of any State containing nontaxable Indian lands, individual and tribal, public domain lands (both reserved and unreserved), national forests, and national parks and monuments, the Federal share, for purposes of this chapter, shall be increased by a percentage of the remaining cost equal to the percentage that the area of all such lands in such State is of its total area;
except that the Federal share payable on any project in a State shall not exceed 95 percent of the total cost of any such project. In any case where a State elects to have the Federal share provided in paragraph (2) of this subsection, the State must enter into an agreement with the Secretary covering a period of not less than 1 year, requiring such State to use solely for purposes eligible for assistance under this title (other than paying its share of projects approved under this title) during the period covered by such agreement the difference between the State’s share as provided in paragraph (2) and what its share would be if it elected to pay the share provided in paragraph (1) for all projects subject to such agreement. In the case of any project subject to this subsection, a State may determine a lower Federal share than the Federal share determined under the preceding sentences of this subsection.
(c)
Increased Federal Share.—
(1)
Certain safety projects.—
The Federal share payable on account of any project for traffic control signalization, traffic circles (also known as “roundabouts”), safety rest areas, pavement marking, commuter carpooling and vanpooling, rail-highway crossing closure, or installation of traffic signs, traffic lights, guardrails, impact attenuators, concrete barrier endtreatments, breakaway utility poles, or priority control systems for emergency vehicles or transit vehicles at signalized intersections may amount to 100 percent of the cost of construction of such projects; except that not more than 10 percent of all sums apportioned for all the Federal-aid systems for any fiscal year in accordance with section
104 of this title shall be used under this subsection. In this subsection, the term “safety rest area” means an area where motor vehicle operators can park their vehicles and rest, where food, fuel, and lodging services are not available, and that is located on a segment of highway with respect to which the Secretary determines there is a shortage of public and private areas at which motor vehicle operators can park their vehicles and rest.
(2)
CMAQ projects.—
The Federal share payable on account of a project or program carried out under section
149 with funds obligated in fiscal year 2008 or 2009, or both, shall be not less than 80 percent and, at the discretion of the State, may be up to 100 percent of the cost thereof.
(d)
The Secretary may rely on a statement from the Secretary of the Interior as to the area of the lands referred to in subsections (a) and (b) of this section. The Secretary of the Interior is authorized and directed to provide such statement annually.
(e)
Emergency Relief.—
The Federal share payable on account of any repair or reconstruction provided for by funds made available under section
125 of this title on account of any project on a Federal-aid highway, including the Interstate System, shall not exceed the Federal share payable on a project on such highway as provided in subsections (a) and (b) of this section; except that
(1)
the Federal share payable for eligible emergency repairs to minimize damage, protect facilities, or restore essential traffic accomplished within 180 days after the actual occurrence of the natural disaster or catastrophic failure may amount to 100 percent of the costs thereof; and
(2)
the Federal share payable on account of any repair or reconstruction of forest highways, forest development roads and trails, park roads and trails, parkways, public lands highways, public lands development roads and trails, and Indian reservation roads may amount to 100 percent of the cost thereof. The total cost of a project may not exceed the cost of repair or reconstruction of a comparable facility. As used in this section with respect to bridges and in section
144 of this title, “a comparable facility” shall mean a facility which meets the current geometric and construction standards required for the types and volume of traffic which such facility will carry over its design life.
(f)
The Secretary is authorized to cooperate with the State transportation departments and with the Department of the Interior in the construction of Federal-aid highways within Indian reservations and national parks and monuments under the jurisdiction of the Department of the Interior and to pay the amount assumed therefor from the funds apportioned in accordance with section
104 of this title to the State wherein the reservations and national parks and monuments are located.
(g)
At the request of any State, the Secretary may from time to time enter into agreements with such State to reimburse the State for the Federal share of the costs of preliminary and construction engineering at an agreed percentage of actual construction costs for each project, in lieu of the actual engineering costs for such project. The Secretary shall annually review each such agreement to insure that such percentage reasonably represents the engineering costs actually incurred by such State.
(h)
Notwithstanding any other provision of this section or of this title, the Federal share payable on account of any project under this title in the Virgin Islands, Guam, American Samoa, or the Commonwealth of the Northern Mariana Islands shall be 100 per centum of the total cost of the project.
(i)
Increased Non-Federal Share.—
Notwithstanding any other provision of this title and subject to such criteria as the Secretary may establish, a State may contribute an amount in excess of the non-Federal share of a project under this title so as to decrease the Federal share payable on such project.
(j)
Credit for Non-Federal Share.—
(1)
Eligibility.—
(A)
In general.—
A State may use as a credit toward the non-Federal share requirement for any funds made available to carry out this title (other than the emergency relief program authorized by section
125 and the Appalachian development highway system program under section

40) or chapter
53 of title
49 toll revenues that are generated and used by public, quasi-public, and private agencies to build, improve, or maintain highways, bridges, or tunnels that serve the public purpose of interstate commerce.
(B)
Special rule for use of federal funds.—
If the public, quasi-public, or private agency has built, improved, or maintained the facility using Federal funds, the credit under this paragraph shall be reduced by a percentage equal to the percentage of the total cost of building, improving, or maintaining the facility that was derived from Federal funds.
(2)
Maintenance of effort.—
(A)
In general.—
The credit for any non-Federal share provided under this subsection shall not reduce nor replace State funds required to match Federal funds for any program under this title.
