Highway Page Updates — 2021

December 16:

December 3: After four years of construction, the billion-dollar I-74 bridge in the Quad Cities was dedicated on Wednesday and the new Illinois-bound span opened to traffic late last night. (News coverage: Quad-City Times, KWQC-TV, WHBF-TV, and WQAD-TV.) Updates have been made to the I-74 and US 6 highway listings, the Highways of Davenport and Bettendorf page, and the I-74 Quad Cities exit list. (While I-74 will be at least six lanes wide from Middle Road through the Avenue of the Cities in Moline, I have not added lane configurations to the exit list yet since work is still going on.)

November 17: Northbound I-29 at the vicinity of I-480 in Council Bluffs has closed through the summer of 2023 to continue reconstructing the interchange with I-480, according to this news release from the Iowa DOT. Since this is a long-term closure of more than a year, I have updated the I-29 south, I-80 west, I-480, and I-880 exit lists accordingly.

November 4:

September 22: According to Street View images taken earlier this month, signing of I-680 has finally removed from the former concurrency with I-29 that existed before the designation of I-880, as all mentions of I-680 along I-29 have either been removed or greened out. The I-680 and I-880 exit lists have also been updated.

September 21:

August 9: According to this Facebook post from the Iowa DOT's Council Bluffs Interstate reconstruction page, the speed limits on eastbound I-80 and southbound I-29 have both been raised to 65 MPH, making the speed limits equal in both directions.

April 24: While I have not received any updates related to the truncation of IA 3 and decommissioning of IA 32 in Dubuque since the beginning of the year, I did stumble upon a YouTube video which confirms that US 52, IA 3, and IA 32 are no longer signed through the city. I have yet to pinpoint a date for when signs were taken down, so I'll mention "early 2021" as the decommissioning date for now.
