May 6, 2009: Colby, Kansas. That’s supposed to be Business Loop I-70. This is just east of where US 24 separates from I-70 after two long pairings in Colorado, and just west of where I-70 angles southeastward toward US 40.

June 25, 2006: Southwest end of MN 23 at I-90, less than 10 miles from the Iowa border. The other end is in Duluth.

July 2, 2009: Pittsburgh area, during the short time I-279 and a newly extended I-376 were co-signed. I-279 was later removed, making a first-digit-odd route a giant loop and a first-digit-even route a spur.

September 18, 2010: The west end of IA 16. Or north end. Whatever. (See the page for an explanation.)

April 20, 2008: Mexico, Missouri. South end of the MO 15 that used to continue into Iowa. This BGS uses the lazy-squiggle state outline for the Missouri state shields.

July 31, 2005: The north end of IA 14 in Charles City, east of here, was (likely) unchanged from its creation in 1920 until 2006, when US 18 was rerouted and two of Charles City’s three interchanges got re-signed. Now … Continue reading →
