Actually when I stay in Jersey... In Union to be exact I drive right past the Vauxhall Rd Entrance..
You can take Springfield ave in Maplewood right to the Vauxhall Rd entrance/exit, I grew up in Maplewood actually most of my childhood.. You would want to take the Maplewood exit which takes you to Vauxhall Rd..The 4 pm till 6 pm time slot for the Vauxhall Rd entrance/ exit is a bear but all them are like that at that time... Springfield Ave runs parallel to Valley St In Maplewood So you can also take Valley Street to Vauxhall Rd..Now Valley Rd is another location in the East Orange/West Orange area..
Morris Ave is another possibility and is within spitting distance of the Maplewood exit
There is no South Orange exit for 78..
Now for the Video.. Its actually Valley Street and Tuscan Rd.. ( the new locals call it Valley Rd for some odd reason as I stated do not get Valley St and Valley Rd confused separate towns as I mentioned )
Never take Valley St during the rush hours its narrow single lanes and they even added a new traffic light or two.. I was just there in September..
I know all the short cuts but being that you do not know the area I'm not even going to confuse you with them
