Interstate 15 was made official in back in 1974. This was a time when people had new gassed up Chevelles and wanted to try and get to Brigham City before Maddox closed. It was previously US 91, but Utah said "let's let loose with a full interstate freeway."

Now we know that I-15 recently boosted the speed limit in certain parts to 80 MPH which makes it one of the fastest freeways in the country. But is it the fastest?

According to San Antonio Express News:

"Texas drivers love to go fast, and no U.S. speed limit is faster than one Texas highways. 

Texas 130 between Texas 45 near Austin and Interstate 10 in Seguin has a posted speed limit of 85 miles per hour. The 41-mile stretch of highway runs through towns that include Mustang Ridge, Kingsbury and Lockhart. 

It's the fastest posted speed limit in the United States, according to the Insurance Institute of Highway Safety. The speed limit is 10 miles per hour higher than the average 75 mph limit on the rest of Texas' highways."

Ok, but that's Texas 130 is a toll highway. So does that count?

If it doesn't than Utah's 80 MPH limit makes I-15 tied for the fastest in the country with a few others.

The other states that have portions of freeway with an 80 MPH limit include the usual suspects who believe in freedom: Idaho, Montana, Wyoming and South Dakota.

God bless those states.

How fast do you drive on I-15 and are you one of those people that treats the HOV lane like a passing lane? Let me know in the comments.
