Federal-Aid Highway Act of 1968
As former railroad owners expanded their investment in shipping through alternative measures, this act expanded the Interstate Highway System by 1,500 miles. It provided funding for new interstate roads, as well as primary and secondary roads so that truckers in partnership with railroads could access more remote areas and expand profitability. Concurrently it led to environmental protections to federal highway projects which allowed the ICC and its supporter’s power to sue or inhibit the development of competing transportation programs, roads, or bridges under the guise of environmental protection.
