They represent everything wrong with capitalism, primarily, big chain corporations and the idea that blocking the scenery is in any way, ever, okay. But for navigational purposes, they can sometimes come in quite handy.
Sometimes states just refuse to cooperate ahem, damn you the South! While not specifically an exception to any rules, I is the only Interstate in the country which runs through a single county.
It runs for This road is riddled with exceptions. Lengthy theories abound about why this route was named as it was and therefore drove all conventions off the side of the road, but suffice to say that though this should be a mere bypass or loop, there is actually no such route as I, and if there were, it would be way south of where I is.
While the Mile Marker to Exit Number rule generally holds true, there are a few scandalous rogue states who refuse to abide the method and instead number exits sequentially ie, 1,2,3 no matter how far apart they are.
New York mostly follows suit. The History Firstly, we should thank our forefathers. Think California, Redwoods and Pearl Jam. Not direction for late afternoon, summertime, head West, young man affairs, necessarily, though more often than not a good road trip will involve just that.
Head South. Route Numbers Every highway has a route number. US Highways. Thor Motor Coach! Click here for more about Axis. California uses a postmile system on all its state highways, US routes and interstate highways. The postmile systems indicates the distance a route travels through individual counties instead of the state.
Most states now post mile markers every. There you sit in the backseat. Mile after mile passes by on the lonesome highway. Every once in a while, you notice a little green sign with a number on it. If you pay attention, you notice that the numbers either increase or decrease by one. What are these things?
Highway mile markers, of course! You can find mile markers along all sorts of highways. Some are local or state highways, while others may be large interstate highway s. As it turns out, mile markers serve several important purposes. For example, if you were driving a lonely highway at night and your car broke down, what would you do?
You would probably call someone for assistance , such as the police. But did you ever stop to think how you'd tell them where you are? Telling them you're on Highway 37 near the big oak tree with the funny bend in it probably isn't going to help all that much.
It also probably won't be that helpful if you tell them you're about miles from the nearest town with an old red barn. If you can tell them you're only about a quarter-mile past mile marker 23, though, you'll probably get the assistance you need fairly quickly.
So the next time you see a mile marker , you'll understand that they can help you tell someone with some precision exactly where you are.

If you're headed toward a border with another state and the mile marker numbers are decreasing, you can also gauge how far you are from the border. Most highways change mile marker numbering at state borders. Mile markers on interstate highways can also help you determine which direction you're going. On most interstates, mile marker numbers begin at the south state line on north-south routes and increase as you travel north.
On east-west routes, the numbers begin on the western state border and increase as you travel east. Keep on driving down the road to learning by checking out one or more of the following activities with a friend or family member:. Thanks for sharing, Lyda!

The Caltrans document included several photo examples with explanations of route shield and direction signs on the 10 Freeway near the Ontario airport placed along the side of the freeway, large green overhead destination signs with white lettering designating which lanes were for various freeways, guide signs telling drivers the distances to the next nearby exits, and exit numbers on signs on the sides of the road.
