Traffic? Yes you certainly will not be alone on the roads.
It's "doable" and in my book at TJC Typical Jersey Commute.
You will hit slowdowns in the usual spots probably like NJ 24 freeway merge then up to I-80,,,but I'm thinking not all too bad afterwards.
I took that ride back when they had HOV lanes on 287 and that was one big BRAKE check, causing 95% of traffic to go from 3 lanes and stop to go to 2 lanes. That was sort of an eco-political deal to get the 3rd lane built on two eights (287) after the top portion was completed.
