But hey don’t get intimidated just yet. The differences are not as tough to navigate through as the I 95 and I 75 to Florida.


The very first thing that comes to mind when talking about roads is its length. 

How much distance does it cover? Does it run through a number of cities? That sort of question, mostly.

Let’s see how the two interstates fare against each other in this category.


The I70 covers a lot of distance despite being the smaller highway in comparison to I80. It covers a lot of ground, about 2,000 miles(roughly around 3.5 thousand km)

I80 is the second longest interstate in the US, covering a span of almost 3000 miles. Which roughly translates to 4.5 thousand kilometers. That’s huge!

As the interstate covers a large area, you can travel to a lot of states using it. You can travel to San Francisco, New Jersey, California, Salt Lake City, Chicago etc, driving through I80.

Both the I70 and I80 share some common cities along the way. You might find it hard to decide whether to choose I70 or I80 from SLC-Denver.

Notable Sights

There’s nothing better than beautiful sights alongside a long stretch of roads. Acres of beautiful lands passing by while you keep driving, it’s the best thing!

Okay. Maybe the I80 doesn’t have as many wonderful places to see as 170. But still, you’ll pass one or two great places when driving through.

Does I 80 go through the mountain?

Yes, it does.

Like Glenwood Canyon, you can see the mountain ranges of Rock springs and occasional deers. There’s also the famous Ames monument in Wyoming that’ll hook your eyes to it.

The drive through I80 can be a bit boring. You’ll have to pass a long stretch of road without seeing anything interesting.


Highways are mostly elevated to overcome some existing complications of terrain and communication. It’s very expensive to build elevated highways. In order to avoid curving hills, forests, and water bodies, this method is implemented.


The I70 highway is way elevated than the I80. This makes the I70 road condition suitable for driving with most vehicles without any major issues. 

Thanks to the elevated construction, I70 can run through various notable places without carving the scene. Thus, leaving no negative impact on the environment.


The I80 is not as elevated as the I70. But it’s elevated to some degree nonetheless. However, it’s not that easy to drive with family vehicles through I80 at times. With trucks being the dominant vehicle on I80, it’s mostly preferred by truck drivers.

Time and Traffic

Some highways are notorious for their long hours of traffic and the frustrations that come with it. In case of I70 and 180, here’s how the traffic is:


There’s one or two spots that you should keep an eye out for while driving through I70. While the highway stays clear mostly, you might get stuck in the traffic during rush hours.

Be aware of driving through Denver during the rush hours. Not taking that in consideration can make you go through hours of traffic.


Unlike I70, there’s no particularly heavy traffic spot on I80. Yes, you might have to drive for hours to reach from one state to another. But you won’t have to deal with traffic on I80 most of the time.

Which Route Do We Pick?

Now that we’ve laid every necessary information on the table, it’s time to choose a winner.

Which is better, interstate 70 or interstate 80?

In for a nice ride paired with beautiful views of the east-west US? I70 is your pick. You won’t be disappointed at all. On your way, you can still reach out to many cities and there should be enough gas stations and restaurants on the way as well.

On the other hand, if you don’t mind long stretches of driving, you should drive on I80. It  might not have the best views, but it’s best for driving with most vehicles. Plus, you won’t have to worry about the traffic as well!

We think that, for occasional commuters, the I70 is the best route. But if you’re used to driving through interstates regularly, the I80 should be your ideal highway.

Using the same metrics, you can decide the better route between I10 vs I40 as well.
