way hazards existing or found to exist at crossings of highways with
railroads, and including the alteration, reconstruction or relocation of
existing underpasses or overhead bridges, and generally to construct, im-
prove and maintain the highway system of this State, with funds received
from the United States Government or any agency thereof under such
terms and conditions as may be imposed upon the use of said funds; and
for this purpose the State Roads Commission may exercise any of the
powers conferred upon it by this Article or elsewhere. The total costs
of any project constructed with funds received from the United States
Government or any agency thereof shall be borne entirely by such funds
as far as the same are available and except insofar as an Act of Congress
or regulations made thereunder may otherwise provide, and, in the event
that the funds so received from the United States Government or any
agency thereof are unavailable or insufficient to pay the total cost of any
such project, the difference between the total cost and the amount so
received shall be borne in the manner now provided by law except as
provided herein. In the event any funds so received from the United
States Government or any agency thereof are used to eliminate highway
hazards or construct new, or reconstruct, alter or relocate existing railroad
or highway underpasses or overhead bridges, the State Roads Commission
is further authorized to separate any grade crossing, or reconstruct, alter,
repair or relocate any underpass or overhead bridge, under or over any
railroad, or otherwise eliminate such hazard, as agreed upon by the Com-
mission and the railroad or railway company. This provision, however,
shall in no way be construed as a limitation on the power or authority
of the Commission to require the railroad to contribute its present statu-
tory apportionment based on the difference between the total cost of the
project and the amount received from the United States Government or
any agency thereof.
