Route 1 Problems?
Stay on the Turnpike a little longer
I'm hearing that the final leg of the trip to Princeton on Route 1 can often be a problem. I suggest staying on 95 South until exit 7A to 195 West. Then take 195 West to 295 NORTH. Then take Exit 67 to Route 1 NORTH, and then take that to the Washington Road exit, which is a traffic circle. Go three quarters of the way around the circle and turn right (between the gas stations) toward Princeton. The campus is located approximately a mile straight ahead.
The above directions leave you on Route 1 for 3 miles instead of 16, which is a big difference.
