Which has more traffic on a Saturday tappan zee bridge or george washington bridge?

We are driving to Ocean city Nj from Mass on Saturday june 27th. I know there is more commuter Traffic on the GW but how much traffic is there on a Saturday? Should i still go the Tappan Zee?

unless there is an accident you should be able to get through both with no problems

NJ traffic congestion: There MUST be a better way!
