Is there Traffic from Bx to NJ in the morning around 7:30am?

Question

And how bad is it? and coming back around 6?

Answer 1

7:30 AM is right in the rush hour (for cars).  6 PM is the evening rush.

Bumper to Bumper on the Cross Bronx and over the George Washington Bridge into NJ in the morning and the same on the return trip.

The Bruckner to the Cross Bx and the Major Deegan to the Cross Bx are no better.  The interchange at the Cross Bx can be even worse than the Cross Bx itself.
