The above image comes from an Iowa DOT sign letting contract that is to be let May 16. The contract covers sign trusses and BGS replacement at four key interchanges: Both ends of I-880 and IA 29 at old IA 192, plus IA 191 at I-880.
Many of the BGSs are getting a complete replacement. This will eliminate the overlaid I-880 shields over the I-680 shields, and also remove the hole for IA 192 on SB I-29 at Exit 57.
Some smaller signs, though, including the relevant ones at IA 191, are getting a greenout overlay. The designation of “Omaha” will replace “North Omaha”. That name has been used since the signs were originally put up, or in the case of the exit near Shelby, after an extension of I-680 replaced I-80N. This project does not include the signs at the Logan/Beebeetown exit or on westbound I-880 at I-29, so “North Omaha” isn’t completely gone yet.
(I still disagree with the redesignation of part of I-680. Bleah.)
