I don't know where in jersey you are starting from----South Jersey take 301 down through MD and you come out North of Richmond----one toll I think and miss DC completely. Take the by pass around Richmond. No way do you want to come down I-95 South of DC Unless you can hit there after 12 and before 3,take the HOV lanes South to below Quantico. Need an EZ pass. I can leave BWI airport and be in central NC or the NC__SC state line in 5 hours normally but I time the traffic and come straight down 295 to 395 hit the HOV lanes and go----timing is everything.
