The Katy Freeway was originally built in the 1950s as a four-lane highway, but was expanded over the years to keep up with Houston’s growing population and economy.


In the 1980s, the Texas Department of Transportation (TxDOT) launched a major expansion project to widen the Katy Freeway to ten lanes, which was completed in 2006. Since then, additional expansion projects have increased the width to 26 lanes in some areas, making it the widest road in the world.
