There is a book about this era and the history of the Interstate system called Big Roads. My gandpa worked on the overpasses on I-94 in North Dakota back in the 50's. Fascinating story to read. We could never build this system again.

That was a trend during the early days of the Interstate Highway System. It was discovered to be more problematic than anything.
I read an interesting book about this a few years ago, called The Big Roads, that talks about this. Very interesting read.
I just finished The Big Roads, last week. It goes into the building of the Interstate system in the US, but with more of an emphasis on the people behind the work than technical specs. Thought it was good

Unfortunately, it isn't on massive Kindle sale anymore :(
Eisenhower gets way too much credit; most of the system had already been planned by the time his name came into it. This is a GREAT book.
