Eisenhower envisioned the Interstate Highway System to move war material. It was not built primarily for the motoring public. An unintended consequence was it took freight off the railroads onto the highways. The proliferation of tractor trailer trucks on the highway has worn the roads out and caused congestion. If the trucks were banned from the roads, while we would have no goods in our stores, we would have a pleasant motorway.
The trucks could be taxed a bit more to help pay for repairs and encourage rail transit. But then there is politics.
