Sometimes better information throws your settled pattern for a loop.<\/p>\n
Part of what I have stated on this website for IA 3’s history<\/a> in Dubuque is wrong. The maps never would have distinguished the difference, but the online route description<\/a>, made available in 2016, does. The state highway never ended at US 61\/151 before the present-day expressway\/freeway was built, according to the route description; its end was officially US 20 from at least 1948 until 1991.<\/p>\n But … that’s a direct contradiction of the primary road sufficiency logs, which I used as the basis for my IA 3 history. How do I solve this? Well, I can’t, unless someone in Dubuque happens to have 20th-century photos of the relevant intersections. I can, however, note the discrepancies.<\/p>\n It makes a mess of some maps I had though. The bright side is, with the route descriptions for US 20, 52, 61, and 151, plus some sleuthing in what’s available online for the Dubuque Telegraph Herald<\/em>, I believe I have been able to reconstruct an accurate history of the highways in Dubuque with just a couple of ambiguities.<\/p>\n The Dubuque Highway Chronology<\/a> is different from others I’ve done because the map covers a relatively small area, downtown. The rest of changes in the metro are mentioned but I felt any bigger size took away from where the important stuff was happening \u2014 especially since so many maps are needed.<\/p>\n The corrections come right up to the present day. I didn’t think that the conversion of certain streets in downtown Dubuque to two-ways in 2014 affected US 52\/IA 3, given the exit configuration on US 61\/151, but I was wrong on that too (and really should have fixed it earlier since I did get a PowerPoint from the DOT about it). It’s actually kind of funny because it’s resulted in a transfer of jurisdiction of one lane but not the other <\/em>of a city street (11th). The east end of IA 3 is where it has been, on 9th Street, but the west beginning technically is 9th now too.<\/p>\n Now, with all the changes, I was afraid I wasn’t going to have good pictures of points I needed. I still kind of don’t BUT I was able to pull from 2007, 2013, 2015, and 2016 to augment not just IA 3 but US 20<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":" Sometimes better information throws your settled pattern for a loop.
