This State Has the Worst Traffic in the U.S., According to Data
You're most likely to find yourself in a jam on the highways of this state, research shows.
![Highway traffic jam](https://bestlifeonline.com/wp-content/uploads/sites/3/2021/10/shutterstock_420463105.jpg?quality=82&strip=1&resize=640%2C360)
Is there anything worse than getting stuck in traffic when you're rushing to get somewhere? Of course, a traffic jam can happen anywhere, but anyone who has spent enough time on the road knows that some cities and states have it much worse than others. To find out where traffic is usually totally valid and not just an excuse for being late, Best Life consulted a 2021 report from TRIP, a nonprofit that researches transportation trends and needs, to determine which state has the worst traffic in the U.S.
In conjunction with the 65th birthday of America's interstate highway system, TRIP released a report that analyzed data to determine what percentage of each state's interstate system is congested with traffic. Using data primarily prepared for Congress by the Transportation Research Board, TRIP also identified, amongst other things, the condition the country's highways and bridges are in. Read on to discover which state with the worst traffic and to learn more about the ways of the road.

Congested interstates: 0 percent
Alaska has the opposite of a traffic problem, according to the TRIP report, with 0 percent of the state's interstate system considered congested.
However, that doesn't mean its roads are in perfect condition: 8 percent of Alaska's interstate pavement is in poor condition, the report found.

![cityscape photo of downtown Bosie, Idaho](https://bestlifeonline.com/wp-content/uploads/sites/3/2021/01/boise-idaho.jpg?quality=82&strip=all&w=1024)
Congested interstates: 24 percent
Nearly a quarter of Idaho's highways are congested, which makes sense seeing as the state has seen a significant increase in the use of its interstate system over the last couple of decades. Since 2000, there has been a 44 percent increase in vehicle miles traveled, which is well above the national average of 26 percent. But even with that increased wear and tear, only 1 percent of the pavement is considered to be in poor condition.

Congested interstates: 31 percent
Oklahoma has seen a 25 percent increase in vehicle miles traveled on the state's interstate system since 2000, which is right around the national average. Yet, the state's 31 percent traffic congestion rate on those roads remained well below the national average for that particular statistic.
32
Nebraska
![cityscape photos of buildings and streets in Omaha, Nebraska](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/11/omaha-nebraska-1.jpg?quality=82&strip=all&w=1024)
Congested interstates: 32 percent
If you're cruising down the highways of Nebraska, there's a one in three chance you'll be hitting some congestion. The good news is, if you're stuck on a bridge, you can be assured it's pretty safe: 0 percent of Nebraska's interstate bridges are in poor condition and only 2 percent have pavement that's considered to be in a poor state.
31
New York
![aerial view of the bronx in new york](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/06/shutterstock_648271807.jpg?quality=82&strip=all&w=1024)
Congested interstates: 34 percent
New York has a below-average traffic congestion rate compared to all the states on this list, and it appears things may be slowing down in the Empire State. According to the TRIP report, New York has only seen an 11 percent increase in vehicle miles traveled on those roads since 2000, well below the national average of 26 percent.
30
Wisconsin
![Scenic Small Town Nestled in Autumn Valley, Beautiful Rural Wisconsin Fall colors.](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/09/wisconsin-state-scenery.jpg?quality=82&strip=all&w=1024)

![baton rouge louisiana from above](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/06/shutterstock_1161171376.jpg?quality=82&strip=all&w=1024)
Congested interstates: 37 percent
Over the last couple decades, Louisiana has seen the second-highest increase in use of its interstate system of any state in the country. In fact, since 2000, the number of vehicle miles traveled on Louisiana's interstates has increased by 61 percent. Still, traffic congestion remained below the national average at 37 percent.
27
Oregon
![Prineville, Oregon](https://bestlifeonline.com/wp-content/uploads/sites/3/2021/08/shutterstock_319074329.jpg?quality=82&strip=all&w=1024)
Congested interstates: 38 percent
Ohio has relatively low traffic congestion on its interstates—considering the national average of 47 percent—and the rest of its metrics are similarly below average or around there. It's seen a 14 percent increase in vehicle miles traveled since 2000 (compared to the 26 percent national average), and only 3 percents of its highways and 1 percent of its interstate bridges are in poor condition (compared to the 3 percent average of each of those factors nationwide).
26
Michigan
![Michigan](https://bestlifeonline.com/wp-content/uploads/sites/3/2021/09/mich.jpg?quality=82&strip=all&w=1024)
Congested interstates: 39 percent
With only an 8 percent increase in vehicle miles traveled since 2000 (one of the lowest upticks in the country), it may come as a surprise that 6 percent of the state's interstate pavement and bridges are considered to be in poor condition, twice the national average in both those categories. Still, its percentage of congested roads is 39 percent, which is below the national average.
25
Nevada
![reno nevada](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/07/shutterstock_231512866.jpg?quality=82&strip=all&w=1024)
Congested interstates: 41 percent
Nevada has seen the greatest increase in use of its interstate system of any state in the past couple of decades. Since 2000, the vehicle miles traveled on those roads have increased by 69 percent. Despite the boom, its interstates remain relatively smooth sailing, with a congestion rate of 41 percent.
24
Arizona
![Phoenix, Arizona, downtown cityscape from above at dusk.](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/08/phoenix-arizona-cityscape.jpg?quality=82&strip=all&w=1024)

Congested interstates: 45 percent
North Carolina has seen an increase of 57 percent in vehicle miles traveled on its interstate system since 2000, more than double the national average. The level of traffic congestion on those roads, however, remained just under the national average of 47 percent, tying with the next state on this list.
22
Tennessee
![An aerial shot of the skyline of Nashville, Tennessee](https://bestlifeonline.com/wp-content/uploads/sites/3/2021/09/aerial-shot-nashville-tennessee-states-worst-covid-surges.jpg?quality=82&strip=all&w=1024)
Congested interstates: 45 percent
Tennessee's interstate roads had the same level of traffic congestion as North Carolina. But it's seen only a 33 percent increase in miles traveled by cars on its interstate system since 2000, and very few of its highways and bridges are in poor condition (1 percent and 2 percent, respectively).
21
Missouri
![The skyline of St. Louis, Missouri](https://bestlifeonline.com/wp-content/uploads/sites/3/2021/06/st-louis-missouri-skyline-covid-outbreaks.jpg?quality=82&strip=all&w=1024)
Congested interstates: 47 percent
Missouri's traffic congestion rate is right at the national average, but where the state is struggling most is with its bridges—5 percent are in poor condition and 71 percent are considered to be fair, which are both below the national averages.
20
Ohio
![city skyline and bridge in Columbus, Ohio](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/11/columbus-ohio.jpg?quality=82&strip=all&w=1024)
Congested interstates: 48 percent
Ohio may be the first state to exceed the national average when it comes to traffic congestion, but in all other areas, it appears to be doing fine: only 3 percent of its highways are in poor condition, and 1 percent of its bridges are considered to be in a poor state, while 33 percent are fair.
19
Utah
![aerial view of logan utah](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/10/logan-utah.jpg?quality=82&strip=all&w=1024)
Congested interstates: 49 percent

South Carolina
![highway in Dillon, South Carolina](https://bestlifeonline.com/wp-content/uploads/sites/3/2021/03/dillon-south-carolina.jpg?quality=82&strip=all&w=1024)
Congested interstates: 50 percent
Along with 50 percent of its interstates being congested, South Carolina's roads and bridges are fairing slightly worse than the national average—which could be because of a 39 percent increase in vehicle miles traveled on its highways since 2000.
17
Kentucky
![An aerial view of downtown Lexington, Kentucky on a clear day](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/07/downtown-lexington-kentucky-coronavirus.jpg?quality=82&strip=all&w=1024)
Congested interstates: 51 percent
In addition to a congestion rate that is above the national average, Kentucky's bridges seem to be showing their age: nearly half are at least 50 years old, three-quarters are in fair condition, and 3 percent are in a poor state.
16
Virginia
![The downtown skyline of Richmond, Virginia just after sunrise](https://bestlifeonline.com/wp-content/uploads/sites/3/2021/01/downtown-richmond-virginia-covid-surging-4-states.jpg?quality=82&strip=all&w=1024)
Congested interstates: 52 percent

![Minnesota](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/10/minnesota.jpg?quality=82&strip=all&w=1024)
Congested interstates: 56 percent
The traffic congestion in is this Midwestern state is just above average, and so are its scores in almost all other areas: percentage of interstates in poor condition, percentage of bridges in poor condition, and percentage of bridges in fair condition. Interestingly though, it only saw a 9 percent increase in vehicle miles traveled on its interstate system since 2000.
13
Colorado
![cityscape photo of Aurora, Colorado](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/12/aurora-colorado.jpg?quality=82&strip=all&w=1024)
Congested interstates: 57 percent

![An aerial shot of downtown Honolulu, Hawaii from the water looking inland.](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/12/downtown-honolulu-hawaii-skyline-covid-under-control.jpg?quality=82&strip=all&w=1024)
Congested interstates: 60 percent
Hawaii's interstate roads are in the worst condition of any state in the country. In fact, 23 percent of the pavement that makes up those highways is considered to be in poor condition, which is much higher than the national average of 3 percent.
8
Connecticut
![Hartford, CT skyline](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/06/CT.jpg?quality=82&strip=all&w=1024)
Congested interstates: 63 percent
Despite a 63 percent congestion rate, Connecticut's interstate roads have seen a pretty consistent amount of use over the last couple of decades. Since 2000, there has only been a 3 percent increase in vehicle miles traveled on the roads and its highways and bridges are holding steady with just 1 percent of the former and 3 percent of the latter being in poor condition.
7
Rhode Island
![rhode island seascape](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/07/shutterstock_560347717.jpg?quality=82&strip=all&w=1024)
Congested interstates: 65 percent
Rhode Island is the only state on this list that saw vehicles miles traveled on its interstates actually decrease since 2000. And while it was only a 1 percent drop, it's probably a good thing for the state, seeing as the traffic congestion rate on its interstates is already the seventh highest in the country.
6
Massachusetts
![boston massachusetts state capitol buildings](https://bestlifeonline.com/wp-content/uploads/sites/3/2019/04/boston-massachusetts-with-state-house.jpg?quality=82&strip=all&w=1024)
Congested interstates: 68 percent
Massachusetts is another Northeastern state to crack the top 10 worst states when it comes to highway traffic. The condition of the pavement on these roads is right at the national average of 3 percent, but the same can't be said for its bridges: 7 percent are in poor condition (compared to the 3 percent national average) and 78 percent are fair (more than 20 percentage points above the 57 percent national average).
5
Florida
![](https://bestlifeonline.com/wp-content/uploads/sites/3/2021/08/miami-florida.jpg?quality=82&strip=all&w=1024)
Congested interstates: 70 percent
Florida has seen a 41 percent increase in vehicle miles traveled on its interstates since 2000, which is likely why nearly three-quarters of its interstates are congested. Still, only 2 percent of the pavement and 0 percent of the bridges that make up the interstate system are considered to be in poor condition.

Congested interstates: 71 percent
Not only does Delaware have a high traffic congestion rate at 71 percent, but its pavement isn't holding up to the challenge, it seems: 9 percent of highways are in poor condition, three times that of the national average.
3
New Jersey
![New Jersey](https://bestlifeonline.com/wp-content/uploads/sites/3/2020/11/nj-e1622064371959.jpg?quality=82&strip=all&w=786)
Congested interstates: 81 percent
New Jersey has the third worst interstate traffic in the country, and, like Delaware, its roads are showing the pressure: 9 percent of highways have pavement that's in poor condition in the Garden State.
2
Maryland
![Interstate 97 dangerous highways](https://bestlifeonline.com/wp-content/uploads/sites/3/2018/06/i97-maryland.jpg?quality=82&strip=all&w=1024)
Congested interstates: 83 percent
Maryland has seen a relatively modest 19 percent increase in vehicle miles traveled on its interstates since 2000, which is probably a good thing since the traffic on those roads is the second worst in the country. Not to mention, 5 percent of the pavement that makes up Maryland's interstates is in poor condition.
1
California
![](https://bestlifeonline.com/wp-content/uploads/sites/3/2018/07/california-i405.jpg?quality=82&strip=all&w=1024)
Congested interstates: 87 percent
Perhaps it is no surprise that California has the worst traffic in the entire country—the Golden State's traffic so legendary, Saturday Night Live had an entire sketch series about navigating the congested highways.
Based on the TRIP report, California's roads are looking slightly worse than Maryland's, too: with 6 percent having pavement in poor condition.
