Here’s some interesting trivia about the interstate system, such as how they’re the interstates and exits are numbered.

Interstate Trivia

Interstate Route Numbering

The Interstate route marker is a red, white, and blue shield, carrying the word “Interstate”, the State name, and the route number. Officials of AASHTO developed the procedure for numbering the routes. Major Interstate routes are designated by one- or two-digit numbers. Routes with odd numbers run north and south, while even numbered run east and west. For north-south routes, the lowest numbers begin in the west, while the lowest numbered east-west routes are in the south. By this method, Interstate Route 5 (I-5) runs north-south along the west coast, while I-10 lies east-west along the southern border.

In two cases, a major route has two parallel or diverging branches. In those cases, each branch is given the designation of the main route, followed by a letter indicating a cardinal direction of travel (east, west, etc). In Texas, for example, I-35 splits at Hillsboro, with I-35E going through Dallas, while I-35W goes through Fort Worth. The two branches merge at Denton to reform I-35. A similar situation exists along I-35 in the Minneapolis-St. Paul area of Minnesota.

The major route numbers generally traverse urban areas on the path of the major traffic stream. Generally, this major traffic stream will be the shortest and most direct line of travel. Connecting Interstate routes and full or partial circumferential beltways around or within urban areas carry a three-digit number. These routes are designated with the number of the main route and an even-numbered prefix. Supplemental radial and spur routes, connecting with the main route at one end, also carry a three-digit number, using the number of the main route with an odd-number prefix.

To prevent duplication within a State, a progression of prefixes is used for the three-digit numbers. For example, if I-80 runs through three cities in a State, circumferential routes around these cities would be numbered as I-280, I-480, and I-680. The same system would be used for spur routes into the three cities, with routes being numbered I-180, I-380, and I-580, respectively. This system is not carried across State lines. As a result, several cities in different States along I-80 may each have circumferential beltways numbered as I-280 or spur routes numbered as I-180.

Interstate Exit Numbers

The States typically use one of two methods of numbering the Interstate interchange exits.

- The Consecutive numbering system – Starting at the most westerly or southerly point on each Interstate route, interchanges are numbered consecutively. Thus the first interchange becomes Interchange #1. Each succeeding interchange is numbered consecutively as #2, 3, 4, etc.

- The Milepost numbering system – All Interstate routes are mileposted beginning at the most westerly or southerly point. The beginning point is milepost ‘0′. If the first interchange on the route is located between milepost 4.0 and 5.0, it is numbered as Interchange #4. The next interchange, if located at milepost 8.7, would be numbered as Interchange #8, etc. With this system the motorist can easily determine the location and distance to a desired interchange.

Ever wonder where the story Rudolph came from? Find out at Snopes.com. In a nutshell, he was created in 1939 as a promotional gimic for Montgomery Ward department stores. There are several differences from the original story, created by Robert May, and the version that we know through the song and cartoon, however.

Rudolph was not one of Santa’s reindeer (or the offspring of one of Santa’s reindeer), and he did not live at the North Pole. Rudolph dwelled in an “ordinary” reindeer village elsewhere, and although he was taunted and laughed at for having a shiny red nose, he was not regarded by his parents as a shameful embarrassment. Rudolph was brought up in a loving household and was a responsible reindeer with a good self-image and sense of worth. Moreover, Rudolph did not rise to fame when Santa picked him out from the reindeer herd because of his shiny nose. Santa discovered the red-nosed reindeer quite by accident, when he noticed the glow emanating from Rudolph’s room while delivering presents to Rudolph’s house. Worried that the thickening fog — already the cause of several accidents and delays — would keep him from completing his Christmas Eve rounds, Santa tapped Rudolph to lead his team, observing upon their return: “By YOU last night’s journey was actually bossed. Without you, I’m certain we’d all have been lost!”
