Only town?

edit

The statement "Nogales, Mexico is the only town to have the same name as its U.S. counterpart." would be incorrect, unless you clarify by adding "on the US-Mexico border". Niagara Falls, Ontario has the same name as its US counterpart, Niagara Falls, New York.

Only Town? Revisited

edit

Another same name pair exists on the US/Mexico border. This is Tecate, CA and Tecate, BC. Tecate, CA is very small but exists. It is about 30 miles east of San Diego and Tijuana.

ADOT & Metrication

edit

Exactly which person or what office at ADOT is the source of the information posted as to why I-19 has metric signing? RCMoeur, 22:42 MST 25 Mar 2006

I am 90% sure that information comes from the same Daily Star article which announced that the Tucson district wanted to change I-19 back to English-unit signs. The link given for this article no longer works, but I recall reading it at the time, and it included a short backgrounder on I-19 metric signs. So the ultimate source for the "part of the 'metric push'" claim is probably a PAO in the Tucson district. Beyond this, the origins of metric signing on I-19 are shrouded in mystery. I don't know who decided that metric signing should be tested on Interstates, or how I-19 was chosen as the test bed. I do know, however, that the 1970's was a very active period of experimentation in metric signing, with Caltrans developing sign specs for dual-unit signs (some of which are still standing), Ohio DOT putting up metric distance signs (of the general format "Columbus"/"150 KILOMETERS") for select major cities, etc. Argatlam (talk) 14:37, 21 February 2009 (UTC)Reply

Were metric speed limits ever posted?

edit

I had often heard that in the 1970s the speed limit signs in I-19 were posted in km/hr, leading to the inevitable confusion of half-soused drivers returning from carousing in Nogales. Is this true? The article says that distances were posted in metric but not speeds; was this always so? ==ILike2BeAnonymous 00:14, 4 April 2006 (UTC)Reply

As far as I can tell, speed limit signs on I-19 have never been posted in km/hr. I was not able to find any information about this being the case. I also used to live in Tucson and I never heard about that being the case. Nebular110 22:23, 24 May 2006 (UTC)Reply

As I added to the main article, the 1980 signing plan included design details for metric speed signs. But there is additional information. The speed signs appear on pages in the plan set which were (at the time) generally reserved for standard sign designs, and had standard sign codes with (M) (for "metric") suffixes. This implies that the sign designs were also part of the then-current edition of the Arizona DOT Manual of Approved Signs. Also, in the construction plans the speed limit sign was not cancelled out, although the advisory speed signs were. This suggests that the metric speed limit signs were installed as provided for in the contract, and it was finaled out, but the metric speed limit signs were changed out by ADOT forces soon after installation either because they were confusing motorists or because there were problems with enforceability. (Regarding motorist confusion and enforceability, however, it has to be noted that all of the speed signs had explicit units, rendered as "km/h" below the circle having the limit value.)

Assessment

edit

The article's RD is pretty lacking when it comes to interstates. It needs to be expanded before it's at B. CL05:36, 25 June 2008 (UTC)Reply

Map is washed out and lacks detail

edit

The map showing the Interstate is washed-out, lacking contrast. It also lacks detail showing the highway. It needs to be replaced or edited with one that is more readable and possibly giving more detailed information. Rapparee71 (talk) 06:55, 6 April 2009 (UTC)Reply

Second shortest after i-97?

edit

According to the government, I-19 is the fourth shortest:

  1. I-73, 12.27 miles, Emery to Greensboro, North Carolina
  2. I-97, 17.62 miles, Annapolis to Baltimore, Maryland
  3. I-99, 53.00 miles, Bedford to Bald Eagle, Pennsylvania
  4. I-19, 63.35 miles, Nogales to Tucson, Arizona
  5. I-66, 74.80 miles, Strasburg, Virginia to Washington, D.C.

Are I-73 and I-99 not considered "primary" routes? --Rfsmit (talk) 00:33, 21 June 2011 (UTC)Reply
