NJ29, I could see combining WarSt and US1, as a parclo variant, into a single point centered at US1.
US1 itself, I'd more or less leave as-is, save for recentering NJ29 on the NJ29 centerline. (PA/NJ matches the state line as shown in ESRI, so I'm fine with "no-build" here.)
Unsure which WarSt you were referencing above -- the one on NJ29 or the one on US1?
NJ NJ29 WarSt, I could fold into a new US1 as mentioned above.
NJ US1 WarSt, I'd say is independently useful for it's connections to/from the local road network.
