\nAugust 2, 2016:<\/strong> These exits for IA 192 and 24th Street are becoming Exits 49 and 50, respectively, heading north on I-29, as the dual divided freeway project advances in Council Bluffs.<\/em><\/p>\n

The two exits on the shared I-29\/80 segment in Council Bluffs are getting new exit numbers tonight, according to an e-mail (and then press release<\/a>) from the Iowa DOT. As part of the Council Bluffs interstate program expanding I-29\/80 to dual sets of “express” and “local” lanes, the ramps come off part of the outer\/local\/I-29 lanes.<\/p>\n

The 24th Street exit will be I-29 Exit 50 and South Expressway (former IA 192)<\/a> will be Exit 49. I-80 Exit 3 won’t go away completely, though, because there will be an exit from westbound mainline I-80 to South Expressway\u00a0before<\/em> the I-29 lanes join the local. The east 29\/80 interchange will be Exit 48 (NB 29 to EB 80) and Exit 3 (WB 80 to SB 29) but unnumbered heading west.<\/p>\n

This “corrects” an anomaly in interstate exit numbering that happens twice in Iowa. Generally, the lower-numbered interstate is supposed to take precedence, which means that these two exits in Council Bluffs should have been I-29’s to begin with, and I-35\/80 around Des Moines should use I-35’s exit numbering. This convention is why the Avenue of the Saints got remarked around Charles City<\/a>\u00a0when US 18 was rerouted, creating an official Mile 218H. One case where the rules were bent for a positive outcome is US 18\/63, where the New Hampton bypass<\/a> uses 63’s exit numbers because 63 is clearly the more important route.<\/p>\n","protected":false},"excerpt":{"rendered":"
