I recently ran into a discussion of the widest highways and a 2018 Houston Chronicle article claims the 26 lane stretch in Houston leads the world:
For what it’s worth, we can lay claim to the world’s widest freeway: The Katy Freeway at Beltway 8 is 26 lanes across.
Here’s how that breaks down: 12 main lanes (six in each direction), eight feeder lanes and six managed lanes. The managed lanes carry mass transit and high-occupancy vehicles during peak hours and are made available to single-occupancy vehicles for a toll fee during off-peak periods…
A few other contenders come close to the title but don’t quite make it, Voigt said, noting that the discussion had come up at the institute when the Katy widening project was completed in late 2008.
“Off the top of my head, the 401 in Toronto is 22 lanes at the widest and I think a part of the NJ (New Jersey) Turnpike is 18 lanes at one point,” Voigt’s email said.
That is a lot of lanes to maintain and I imagine the highway takes up quite a bit of space (and woe to those located right next to this stretch of road). Driving here must be an interesting experience, particularly if the driver is used to narrower highways.
Is it a surprise that this is in Texas, where everything is bigger and people like to drive, and in Houston, the quintessential sprawling and growing city with no zoning regulations?
It would be interesting to get a more in-depth history of this particular stretch of road. How many lanes did the highway initially have? Who approved the construction of so many lanes? Is there consensus that this was a positive move for traffic? How much money has been spent on this stretch (and that could have been spent on other transportation options)?
