In the west, US 46 is a two-lane road, while in the east, US 46 is a four-to-six lane Jersey freeway and/or expressway, and joins with US 1-9 for one of only two New Jersey triplexes (to find the other, find Clinton). For awhile, US 46 either crossed the Delaware or Columbia Bridges into PA, or later on used the Delaware Water Gap section of I-80 before the Interstate Highways were created. Now, though, it runs from I-80 Exit 4 to the NY state line on I-95/US 1/US 9. Why it doesn't just end at 1-9 is beyond me, since NYSDOT will clearly never embrace 46 as its own. Given that it's just in one state, not to mention that it's north of the correctly-numbered US 22, it should just revert to the still-available NJ 6.

The first and last eastbound shields for NJ 159, old US 46 through a small part of Fairfield. There is original curbing where 159 departs northward from Bloomfield Avenue that only matches curb on original expressways like US 46, supporting evidence that 46 went this way.
