Mile Markers in Colorado

Colorado is one of the homes the Rocky Mountains occupy. If you are traveling here by car through Utah, New Mexico, Kansas, Wyoming, or even Nebraska, it might be helpful to know what locations you might pass along the way. I will just briefly list cities on each interstates and the exit numbers that connect with it.

Remember that exit numbers aren’t just made up. They represent at what mile of the interstate you are at. For example, if you are at mile marker 100, and you find an exit, you will notice the exit number will be the same or off just by a mile or two. If you are traveling west or south, the numbers will count down until you reach a new state or the end of the highway. It will be the opposite if you are traveling north or east on the road. 

Knowing this information, you can take the mile marker you are at as well as the exit number you are looking for and do the math. If you are at mile marker 88 and are traveling to a location with the exit number being 256, that means you are 168 miles away from your destination. It might be another two and a half hour trip assuming traffic is good and you make less stops along the way. So, with all of that being said, listed below are cities all in Colorado you will find along each interstate and what exit number they are at. Note that not every single one you can possibly find is listed. I hope you will find this useful someday.
