It is the sense of Congress that each State should 
prepare a corrosion mitigation and prevention plan, for a 
project for construction, replacement, or rehabilitation of 
a bridge, that includes the following: 
(1) An estimate of the expected useful life of 
the bridge. 
(2) An estimate of environmental exposure of 
the bridge, including marine, deicer application, in-
dustrial, rural, rainfall, temperature, freeze-thaw, 
and other factors that influence corrosion prevention 
and corrosion mitigation strategies. 
(3) An identification of the functional classifica-
tion of the bridge. 
(4) Details of corrosion mitigation and preven-
tion methods that will be used with respect to the 
bridge, taking into account— 
(A) material selection; 
(B) coating considerations; 
(C) cathodic protection considerations; 
(D) design considerations for corrosion; 
and
(E) concrete requirements. 
(5) Details of a project maintenance program 
for the life of the bridge.
