How did they come up with the numbers? Random?
2007-01-24 07:03:41 · update #1
The interstates are numbered, somewhat orderly, odds going north and south, evens going east and west. The evens begin in the south (I-10) and get larger as you head north. The odds begin out west (I-5) and get larger as you head east (I-95).
For bypasses on interstates, the first number even means around a city, the first number odd means through a city.
In DC - I-95 goes north south, the beltway around DC is 495;
the highway through the middle is (partially) 395. This part of the numbering convention is not as closely adhered to as the E/W or N/S one.

As the road ways developed the US gov decided to name them odd # for north and south and even for east west.. They all began from Wash DC.. the discovey channel did a great show on American roads really they hve only been usable since WW1 before that they were used by trucks almost 99 per cent..

I don't know WHO, but my father taught me that, in general, the even numbers run east-west and the odd numbered ones run north-south. Sure, there are curves, etc., but check it out, it's true!
