A 1936 constrution would seem more fitting (ask your self how many hoovers run off it?) I think that the earlier date is the proposal date. i can check with New jersey history society but most references they can provide will not be web linked. I can't edit the article myself because it upsets my suggestbot. Mike
It's more complicated than that. The roads already existed; AASHTO approved an extension of the existing US 322 over those roads into New Jersey at some point in the 1930s. At least one personal site states 1936 as the year, but it often goes by commercial maps, which can be outdated by several years.
What is probably needed here is a reference from AASHTO saying when it was extended, something from one of the two states that marked the extension, or a newspaper article about it.
