(a) The Department of Transportation is hereby directed to replace all bridges on the State highway system containing long through truss spans over 125 feet long with less than a 12 feet clear roadway width. The Department shall initiate a bridge replacement program as soon as possible and shall complete the replacement program of all such bridges by June 30, 1980. All such bridges now on the State highway system shall be replaced except those on roads where the traffic volume is low and the elimination of the bridge would be a minimum inconvenience to the public and the replacement cannot be justified. Such bridges not replaced shall be removed and taken off the State highway system. Provided, that the provisions of this subsection shall not apply to any bridge which has not been removed and replaced by June 30, 1980; these bridges shall continue to be included in the State Highway System, and shall be examined, repaired if necessary, updated and put into usable condition with weight limitations as safety may require.

(b) The Environment [Environmental] Policy Act contained in Article 1 of Chapter 113A shall not apply to the bridge replacement program provided for by this section. (1975, c. 889; 1977, c. 464, s. 7.1; 1981, c. 861.)
