Why America May Be Finished Building New Beltways
Aug 31, 2026
I'm here in Indianapolis, Indiana.
This is a midwest city with a very circular design.
I also went to Lexington, Kentucky because these two cities are home to important beltways,
mainly I-465 in Indy and State Route 4 in Lexington.
These beltways provide efficient access around the metropolitan area and a bypass for the
downtown for drivers who don't want to deal with the high traffic volumes of the inner
cities.
When I drove through Indianapolis this week, I used the beltway to avoid I-65, which goes
straight through the city.
So it's an overall helpful way to alleviate traffic, and it's pretty efficient, right?
Well, there's also some criticisms.
Some say the roads simply help us drive in circles around cities and encourage car usage,
and others point out that we can't just keep building beltways as cities get bigger and
bigger.
These are two very reasonable ways to look at the usage of these ring roads, but either
way they're still being built in cities across the country, and that begs the question, how
long will we keep doing this?
Is the idea of a beltway going out of style, or will it be useful for decades to come?
Today I want to go over that idea and come to a conclusion on the future of this design.
Before I get into that though, I wanted to quickly ask if you would please consider subscribing
to the channel.
I'm very very close to 100,000 subscribers, which has been my lifelong goal.

Thank you!
So as I said before, beltways are useful tools for urban and suburban transportation.
They're circular highways that go fully around the cities, or technically around half
of the city in cases that are limited by water, basically giving more options for the traffic
that directs more vehicles away from the downtown area.
As far as highway designs go, this is about as basic as it gets.
It was used in ancient times for military and trade purposes, and European cities like
Paris built ring roads where the city walls once stood.
So if you wanted to know why Paris' inner ring road exists, there you go.
The idea then developed in the US at the same time basically anything interesting in the
US transportation occurred, which was post-WWII when suburbanization began.
These suburban neighborhoods forced cities to expand outwards at rates never seen before,
and metro areas suddenly took up significantly more area.
American cities were no longer reliant on the downtown to survive, so the idea of constructing
beltways to bypass these already crowded central business districts and support increased suburban
growth developed and turned into action with the passage of the interstate system, which
provided the country with a comprehensive plan of how their highways would be built
and what ideas they wanted to push with this.
The first interstate beltway was I-695 in Baltimore, Maryland, which was completed in
1962 and stretched 51 miles around the city.
Shortly after, the capital beltway was completed around the DC metro in 1964, and that's still
one of the nation's longest at 64 miles.
Over the next few decades, cities like Atlanta completed a beltway, Houston completed a beltway,
and suddenly most large metros in the country had one of these looped roads planned.
So that brings us to the present day situation.
Beltways are very important to most cities, and most major metros either have a completed
beltway or a different form of freeway network that forms a circle.
An example of a large beltway would be Kansas City, and usually the flat midwestern cities
that don't have to deal with terrain or topography are the ones that end up having the most complete
freeway rings.
Somewhere like Atlanta also has quite a long one, and in these southern cities, these beltways
can get really bad traffic, especially in certain areas, such as I-285 near the airport.
An example of cities with this circular form would be Minneapolis, which has plenty of
different freeways in the metropolitan area that come together to form what could be called
a beltway.
This doesn't mean every city is like this, though.
Nashville, Tennessee only has a half beltway, with the north part of the city being much
less populated.
And Sacramento, California has nothing of the sort, though I'll mention this later.
Because first, I want to use Houston as our example for this video.
So Houston is home to two main beltways, I-610, the inner beltway, and the Sam Houston tollway,
which would be the outer beltway.
It's important to keep in mind that this outer freeway is already the longest fully limited
access ring road in the nation, so what happens when they decide to build yet another beltway?
This is what the city is doing with the Grand Parkway, which currently stretches 176 miles
around the outskirts of the city, and it's set to be expanded even farther.
This parkway has cost 1.9 billion dollars so far, and this will push to maybe even 3
billion dollars by the time it's all said and done.
This shows you how extensive of a project it is, and it could be paving the way for
America's future.
North Carolina has followed this during the 2000s, constructing a new beltway around Charlotte,
Greensboro, and now Raleigh, which they're in the process of finishing.
These three massive projects total around 6.4 billion dollars, and this is currently
happening.
So if you have the mindset that freeways are an idea of the 60s and 70s, this is a reminder
they're still being built in suburban areas all over.
Even in California, a state with very different politics, the Southeast Connector is being
built in Sacramento to help offset traffic in that part of the metro.
This corridor has been approved at 34 miles long, and it will begin to cover the metro
that notably doesn't really have a beltway.
Even Lincoln, Nebraska has been working on their own beltway.
They finished the southern part of it in the last few years, and the environmental impact
statement has been approved to expand this north to I-80, which would give the city a
mostly complete beltway.
This is in no way a massive metropolitan area, but they're still growing, and they're
building a beltway to help with it, and this ends up just begging the question of when
these projects will stop getting approved.
Cities are expanding at insane rates, like Houston which has expanded its metro area
by miles upon miles of land in the last few decades, and suburbs are just pushing this
land consumption that encourages the building of beltways and suburban freeways.
So what are things going to be like in 30 years?
Atlanta originally had a plan for its perimeter, which is its beltway, to stretch around 25
to 30 miles farther outside the metro than it ended up doing, covering the entire north
part of Georgia, basically.
Atlanta is booming in population, so it's not entirely impossible something like this
could get approved if the environmental impact isn't too large.
Are we going to see beltway projects like that in cities like Orlando or even Phoenix
as they expand outwards?
It's entirely possible.
If Texas can construct an over 200 mile beltway like the Grand Parkway, so could any other
city.
You gotta think that as suburban growth continues, pretty soon some cities that's more open
to the idea of freeways are going to bite and build another longest beltway in the country.
But maybe they won't.
My argument here is that if cities get too big, these projects will simply be too expensive
to complete.
I don't think many states can get 6.4 billion dollar freeway projects done like in North
Carolina.
And sure, traffic is a big issue, but I don't really see a world where a massive 300 mile
beltway gets built around Portland, Oregon.
Furthermore, a lot of the nation's fastest growing cities are in the west, where massive
projects like this end up being way harder with the possible environmental impacts that
would come from a mega highway around Las Vegas that flattens a mountain and puts a
bridge over Lake Mead.
I simply don't see it as an option for this to continue forever.
But to answer the simple question of the video, no, America isn't done building beltways.
Mostly because in a lot of cases, it works.
These highways reduce suburban traffic, and simply letting these car-dependent suburbs
expand without freeway infrastructure ends up with terrible traffic anyway.
So cities may keep using the tactic as long as it's viable.
