Alternate vs. bypass

[odditude]

As far as I know, New Jersey has only one bypass in the entire state.

generally, NJ provides a new number to one of the two routes instead of using a bannered route.
examples: CR 691 for original routing of CR 541 in Mt Holly, NJ 347 as alt route for NJ 47, NJ 156 for original routing of US 130 in Yardville

Wisconsin seems pretty liberal about using Alternate for most of their interstates, at least in the Milwaukee area.

It's a statewide system, but the purpose of WI's alternate routes is more for emergency/construction usage than being an alternate routing in the sense of these other examples. (Not saying it doesn't belong in the thread, of course)
