The 5 Most Congested American Highways, Where No Bumper Is Safe

If there’s one time we’d recommend using our systems, it’s during your commute home on that busy highway you have no choice but to take.

Though you may be sitting in traffic for a while, it’s still possible to get scratched, side-swiped, rear-ended, or even worse–so who wouldn’t want a good set of sensors to get through that?

With the help of ATRI, we’ve compiled the top 5 busiest highways in the U.S. (as of 2021) that are sure to have you sitting and seething. That is, if you make it home unscathed.

5. Houston, TX: I-45 at I-69/US 59
Though up 53.7% in peak average speed from the year before, the I-45 is the 5th most congested highway in the country and took honors as one of the deadliest in the country as well.

4. Atlanta, GA: I-20 at I-285 (West)
Ranked as the fourth most congested highway on this list, the I-20 average peak speed could be much worse, at 40.9 mph at peak times. Some of us wish for that kind of pace on the way home from work.

3. Atlanta, GA: I-285 at I-85 (North)
Atlanta’s other entry into this countdown puts the I-285 at 3rd and with a definitively slower peak speed than A-town’s previous entry (at 34.4 mph).

2. Cincinnati, OH: I-71 at I-75
The second most congested highway is the I-71 in Cincinnati, with an average speed of 40.1 mph at peak times.

1. Fort Lee, NJ: I-95 at SR 4
The top honor goes to the infamous I-95 in Fort Lee, NJ. The most congested highway also boasts a whopping 31.3 peak average speed, which is guaranteed to get you nowhere really fast.
