This is true for most states. If it crosses a border, numbering begins over at 0 at the southern or western border increasing to the north or east. The MUTCD would permit miles or kilometers, but many states have laws requiring Customary measure for traffic control. If it begins within the state, 0 is at the southern or western end increasing as above.
There are special situations when roads join, then split off again. ________________________________ From: Martin Vlietstra <[email protected]> To: U.S. Metric Association <[email protected]> Sent: Mon, December 28, 2009 3:03:34 PM Subject: [USMA:46314] Freeway Exit Numbers I understand that most US freeway exits are numbered with reference to the number of miles from the state line (or the start of the freeway concerned). In the Wikipedia article “Exit numbers” (http://en.wikipedia.org/wiki/Exit_number), I saw the following: “ United States- The use of sequential or distance-based exit numbering currently varies by state, with 43 states using distance-based exit numbering and seven states using sequential numbering. The latest edition of the Manual on Uniform Traffic Control Devices (MUTCD), issued by the Federal Highway Administration on December 16, 2009, eliminates the option for states to use sequential exit numbering, and requires the seven states that presently number their exits sequentially to convert to distance-based numbering by January 2020.” There is more in the Wikipedia article http://en.wikipedia.org/wiki/Exit_numbers_in_the_United_States. Anybody have any comments? ________________________________ From:[email protected] [mailto:[email protected]] On Behalf Of Victor Jockin Sent: 28 December 2009 19:34 To: U.S. Metric Association Subject: [USMA:46312] Re: Column by Terry Dickson This half-serious piece is ignorable. I just wish the international pressure he mentioned actually existed, or that the President had any inkling to act on the issue of metric conversion. I've said a few times on this discussion group that the biggest problem is the combination of the undemocratic nature of the US Senate (single senators can block action) and our inherently corrupt campaign finance system (Senators use that undemocratic power to serve monied private interests). The result is an inability of the US Congress to act in the public interest when powerful private interests might be harmed. This is both why the US stands alone among industrialized countries in not adopting the world's standard system of measurement, and why we stand alone in not providing universal healthcare for our citizens. The current healthcare debate has placed this glaring fault in our democracy in full view once again. We don't need a revolution to change this, just common sense campaign finance reform and, as Thomas Friedman wrote in the NY Times last week, a change in Senate rules to end filibusters. Neither are unthinkable.

We'd have to convert miles to kilometers and dabs and smidgens to deciliters and centiliters. Is this an important column that deserves a response?
