Semis in the sky

Ohio Airships would like to see highway spending diverted to the airship industry: "The most profound difference between Dynalifters and other trans-continental modes of transportation is the low cost of ground infrastructure. It is a little known fact that a $100K semi-truck is traveling on a $1T highway network. Despite their relatively high unit cost of $100M per aircraft (compared with a semi-truck), Dynalifters require almost no ground infrastructure (only short runways)."
