Nothing ruins holiday plans like being stuck in traffic, but it looks like New Yorkers pretty much have no choice. The city will suffer the worst backups in the nation tomorrow, according to Seattle-based traffic monitoring firm INRIX.

Los Angeles typically takes the crown, but as everyone flees the city one last time for the summer, historic data shows we are in for some serious delays. Coming in third is our neighbor to the north, Bridgeport, Conn., which, being trapped between us and Boston on the I-95 corridor, gets it from both sides.

The worst trip possible, not surprisingly, is out to the Hamptons, which will take up to four and a half hours during the worst travel times for people taking the Long Island Expressway. The Sunrise Highway is slightly better at 3 hours and 40 minutes. Under normal circumstances, both trips would take a little over two hours.

What came as a bit of surprise is that probably for the first time ever, the Jersey Shore is a better bet–and not just at the craps tables. Trips to Atlantic City take nearly half the time of those to the Hamptons, about 2 hours and 37 minutes. That is compared with 2 hours and 12 minutes on a normal trip. If they know how to do anything in Jersey, it’s drive.

As for when to hit the road, well, you probably should have already, but there is still time to beat the traffic. Go. Now. By 4 p.m. on Friday, traffic will reach its worst point, calming, but not by much, 4 hours later. It worsens again around noon on Saturday, and will drag the rest of the day.
