Lyndon Johnson actually said...

I urge all Americans to give recognition to the value of highway transportation to their own activities and to our national welfare.

It was nothing less than to transform the life of an entire continent.

I have called for a major effort to beautify our highways and roadsides, and to construct scenic and recreational roads.

And if we have not really reached the farthest limit of expectation, we have done much more, indeed, than many ever believed we could do.
