I remember "some" states numbering exits in sequence(ascending S->N and W->E) instead of by mile marker, but it seems "most all" have changed to using the nearest mile marker and adding sub-exits sequenced by letter. __________________________________ NRA Benefactor I lost all my weapons in a boating, umm, accident. http://www.aufamily.com/forums/ | |||

Yes, Pennsylvania used to be that way. . | |||

I-90 in South Dakota has it's exit numbers correspond to the miles from the western border with Wyoming. https://iexitapp.com/exits/Sou...0Dakota/I-90/East/53 Certifiable member of the gun toting, septuagenarian, bucket list workin', crazed retiree, bald is beautiful club!

As Black Talon mentioned the I 50 and 60 on that map don't exist due to the fact that they would have run nearly on top of the existing US Highways 50 and 60 causing confusion. | |||

how does Hawaii have "interstate" hiways? . | |||

Yes, it was adopted as a standard exit numbering scheme in the 90's IIRC. prior to that many schemes were in use, most often incremental numbering from one end to the other (inconsistently N-S or E-W). I don't know how they decide which end to start numbering the mile markers, and thus the exits from, but it seems to reset at each State line. I find it useful to monitor the small mile markers as I go along so as to anticipate the distance to the exit I want. | |||

Yes The state's four Interstates, all located on O'ahu, are built to mainland standards unlike their counterparts in Alaska and Puerto Rico. Living the Dream | |||

When giving directions to the directionally challenged, the North/South heading on the Snyder is always difficult. Instead of trying to convince them that South is merely a word on a sign, that has nothing to do with the compass built into the touch screen, I stick to Left/Right. Don't get me started on Waddy/Peytona.  | |||

Didn’t they also lay them out so that they could be used as emergency runways for WWIII if that broke out? They took a lot of ideas from the German Autobahn is my understanding. You also see it still referred to as the “Eisenhower Interstate Highway System” in some places. | |||

Don't Panic |
Yep! Two more fun facts. Lieutenant (later General, later President) Eisenhower commanded the first US Army attempt to get a motorized convoy across America in the summer of 1919. Let's just say he was unimpressed during his two-month journey.  There are many articles, this one is short and sweet.Ex-Lieutenant, then-General (later President) Eisenhower commanded the Allied army that in 1945 found using the Autobahn made transport much simpler. | |||

I recall a popular claim stating that within each five mile segment of each interstate highway, there had to be an unobstructed one-mile stretch that was suitable for aircraft use, i.e. a 5,280' (minimum) runway. All through my years as a commercial pilot & flight instructor, I tried to verify this. I was never able to find any indication that this was true, and in particular, I was never able to find any markings, not on aeronautical navigation charts, no markings on any highways that I have driven on, no markings on the highways discernible from the air, no supporting documentation whatsoever. A few years ago I read (sorry, I don't remember the source) that this claim was just an Olde Wives' Tale, and I do believe that this is actually the case. No pilot I know, and I must be acquainted with hundreds, has ever mentioned finding proof of the alleged runways embedded in the Interstate highway system. I'm pretty sure that they don't exist. הרחפת שלי מלאה בצלופחים | |||

Another Eisenhower freeway connection : as a young officer circa 1919 or so, he was on a detail assigned to drive from East to West coast. The convoy took IIRC "8 weeks" across much of the West that really had no or few connective dirt trails let alone paved hiways. It too seemed to have an effect on future plans. Someone may want to fact check this. | |||

My man Ike engineered the Highways to accommodate 2 Military Deuce and a Halfs going 80mph. I can't remember where I got that info or if I just made it up, but either way I should be able to do 85 all day traveling the big blue signs.  | |||

When I was first stationed in the DC area in the late 1960s, if driving on I95 from the south and stayed on it expecting to go around the city or at least remain on a limited access highway, one ended up in a residential area and looking around wondering if anyone would find your remains, especially after dark. As mentioned above, they finally figured out that it would be best if I95 were part of the beltway to the east, and the signs were changed. Eisenhower’s influence on establishing the Interstate system is remembered by the name of Eisenhower Tunnel on the (now) westbound lanes of I70 at an elevation of 11,000+ feet in Colorado. The other part of the tunnel is labeled for Edwin C. Johnson, a former governor and senator. ► 6.4/93.6 “Most men … can seldom accept the simplest and most obvious truth if it … would oblige them to admit the falsity of conclusions … which they have woven, thread by thread, into the fabrics of their lives.” — Leo Tolstoy | |||

| drop and give me 20 pushups |
Any other place in the United States that this happens???...Intestate I-10 east bound after passing over the Mississippi River Bridge eastbound it enters Baton Rouge, Louisiana the interstate narrows down into a 1 lane roadway.. This is due to the actual design of roadway for everyday traffic flow and has been this way for many years. Wonder why the designers and engineers could let something like this happen... Major causes of massive traffic jams every day especially during rush hour traffic.......................drill sgt | |||

I-24 is supposedly E-W but actually runs more north/south starting near Marion, Illinois and ending in Chattanooga, TN. | |||

I spent seven years in New York and could never figure out their mile markers. You could never figure out where you were or how far you had to go. I much prefer the system used in most states (that don't have their heads up their ass), wherein they begin at 0 at the southernest and westernest point. ________________________________________________________ "Great danger lies in the notion that we can reason with evil."
