Exactly -- the key is to get from that filing to final design in an accelerated fashion to enable construction to begin -- there is no reason why it should take a decade to start pouring concrete on this or any road projectHaving dealt with EISs in projects I managed, the shorter time frame makes a lot of sense. They can cover everything in 24 months.
Remember that Eisenhower*1 lived to see most of the key pieces of the Interstate System [his baby] completed [he lived until 1969] -- and construction only began in 1956
“Our unity as a nation is sustained by free communication of thought and by easy transportation of people and goods. The ceaseless flow of information throughout the Republic is matched by individual and commercial movement over a vast system of interconnected highways crisscrossing the country and joining at our national borders with friendly neighbors to the north and south.
Together, the united forces of our communication and transportation systems are dynamic elements in the very name we bear—United States. Without them, we would be a mere alliance of many separate parts.”
President Dwight D. Eisenhower
February 22, 1955
“More than any single action by the government since the end of the war, this one would change the face of America with straightaways, cloverleaf turns, bridges, and elongated parkways. Its impact on the American economy—the jobs it would produce in manufacturing and construction, the rural areas it would open up—was beyond calculation.”
