Are all US interstate highways "Eisenhower" highways?

Question

I just came from a trip where some rest stops marked the interstate with an "Eisenhower" sign, but others did not. Are there different highway systems in the US?

Answer 1

yes. the interstate system was dedicated as a manorial to pres Eisenhower who signed the authoring law
