The real problem for the last few years has been the new bridge construction over the Mullica River near New Gretna. If it is done by now you can just scoot along the shoulder of the combined Garden State Parkway/US9 for the 2 1/2 miles. I used to do this many years ago. Both times I was passed by police cars who ignored me. If the construction is still going on (ask in New Gretna) you will have to detour west through Egg Harbor City and Mays Landing. This stretch is almost eerily devoid of traffic and people.
