This photo essay details the construction of the original Interstate Highway System in Vermont’s picturesque and largely rural mountainous region through the late 1950s to late ‘70s. During this short time, contractor driven construction equipment innovation was remarkable: 2 1/2 cubic yard shovels were replaced with 4-8 yard shovels and then by massive wheel loaders up to 17 cubic yards; 15-22 ton rock trucks were upped to 50 tons; rudimentary spreading methods with dump trucks using tailgate chains were replaced with CMI Autogrades; and many contractors devised and built ingenious contraptions to increase production. The work attracted many large established road building firms from other States—Lane, Perini, Palazzi, L. G. Defelice, Green Construction from Des Moines, Iowa, as well as.
