Anyone who has ever driven a car in the USA knows that the numerous highways are sometimes gigantic in size. Five lanes in each direction are not uncommon. But there is one section of highway that is so gigantic that it is unparalleled anywhere in the world: the Katy Freeway.
What the autobahns are in Germany and Europe, the interstate highways are in the USA. Often covering gigantic distances, they connect the numerous cities and states of the third-largest country in the world.
Overview
Endless Expanses on the Interstate Highways
Interstate 10, for example, runs for an enormous 3860 kilometers and connects the east and west coasts. If you started at the Pacific Ocean in Santa Monica, California, you could cross the states of Arizona, New Mexico, Texas, Louisiana, Mississippi, and Alabama on the so-called “I-10” and finally, at the end of the really long road trip, you would be at the Atlantic Ocean, in Jacksonville, Florida.
But not only is the length of Interstate 10 enormous, but its width is also spectacular. At least on one very special section, which is located in Texas: the Katy Freeway. This is the name given to the stretch from Houston towards the suburb of Katy. The freeway has been continuously expanded on this section, most recently in 2008 to a gigantic 26 lanes. According to some US media, such asCN Traveler, this makes it the widest highway in the world. However, the medium also points out that the 26 lanes also include the four feeder roads in each direction.

Why Even the Supposedly Widest Highway in the World Cannot withstand the Traffic
It was said that the gigantic highway was necessary because the route is particularly frequented by commuters. Numerous traffic jams made journeys to and from the city of two million people a burden. After the expansion almost 15 years ago, it was initially said that the problem had been solved. The New York Times quotes officials from the Texas Department of Transportation as saying that the expansion of the Katy Freeway would continue to provide the necessary capacity to keep pace with the expected population growth in the greater Houston area.
Scientists Have Been Warning for a Long Time
However, instead of permanently relieving the traffic system, the opposite happened: according to “Business Insider“, traffic volumes actually increased considerably between 2011 and 2014, as even more vehicles were now able to use the additional lanes. The phenomenon was foreseeable. Scientists had already pointed out in the 1960s that wider highways would not solve the traffic problems.
