The communite via the GSP to Union from Howell during high times is what can be excpected - hgih traffic as many homewoners live in South Jersey and work 'up north". However, the Union Toll Plaza is almost always jammed so I'd add another 15 minutest to your commute, Of course this is give or take any particular day. Google maps tells me that the communute would be 56 minutes, but again I'd ad another 15 minutes give or take due to the Union toll plaza jamm.
Hope this helps. If you have any further questions, please do not hestitate to contact me direct @ 732.6065.2931.
