The Busiest Road in Every State

These popular motorways cause 3 million hours of delays each year.

circle

According to a 2017 report by international data company Inrix, the average American spends 41 painful hours (a whole workweek!) in traffic a year. And, in Los Angeles, the world’s most congested city, commuters spend up to 92 hours in traffic jams. With stats like that, it’s no surprise that we’ve come up with exaggerated terms like “Carmageddon” in reference to our roadways. But which of the nation’s roads are responsible for the most exasperating traffic buildups?

To find out, we started with the American Highway Users Alliance’s roundup of the nation’s 50 roadways with the most severe bottlenecks. The list details the cities and exact locations where these nasty bottlenecks occur, as well as the average length of the buildups and the annual total delays they cause. Next, we looked at the Federal Highway Administration’s most recent report to determine each offending highway’s mean annual average daily traffic data, or the average number of vehicles traveling over that section of road each day. Several of the less populated states don’t experience bottlenecks massive enough to be included in the AHUA report (lucky them), so for those states, we’ve reported the interstate with the highest average daily traffic. We’ve also noted the specific city where the road is located, when applicable. (Note: With so many variations in how each city collects traffic data, those popularly crammed local roads, like New York City’s FDR Drive or Boston’s Storrow Drive, didn’t make the cut for this research.)

So take a deep breath—no need to heighten your traffic-induced tension—and make sure you’re nice and relaxed before looking at the jaw-dropping numbers for the most frustratingly congested roads in every state. And for more coverage on the nation’s roadways, don’t miss the 30 Most Dangerous Roads in America.
