It's a stretch of road I know very well. A new report by the American Transportation Resource Institute has named the intersection !-95 and Route 4 in Fort Lee the #1 place in America for truck related traffic jams. The study included 1 million trucks with GPS and looked to 300 locations. On a typical day the average speed on Route 4 approaching the George Washington Bridge is down to 21 miles per hour.
New Jersey I 287 in Piscataway also made the top 10. The Long Island Expressway through Queens came in at number 8. Other studies have given the #1 ranking for congestion to the 7 mile section of Cross Bronx Expressway between the George Washington Bridge and exit 6A.
When my daughter moved to Long Island 5 years ago I had to get used to driving in the city again. Route 4 is a familiar part of my childhood because it was the way to get to Paramus from my hometown of North Bergen. The highway has narrow lanes and is much more congested now. The problem is widening Route 4 is not possible because it travels through residential Bergen County towns.
My vote for the worst stretch of highway in the U.S. would be the Cross Bronx Expressway heading to the George Washington Bridge. Every weekday from 7AM to 9PM you can count on traffic moving at a crawl.
My answer to all this: Whenever it's possible I take the train!
