Highway Page Updates

This is a list of updates to all of my highway pages so everyone can see what is new or what has changed since they last visited. The most recent updates are listed first.

April 15: After reviewing the Iowa DOT's new Des Moines Area Interstate Projects page, I updated the I-35, I-80, and I-235 highway listings to show what work is being done from now through 2028. As for the last left-hand exit from I-80 west to I-235 west, it is part of the preliminary "full-build conceptual layout" released by the Iowa DOT in 2017 which is now linked from these listings, but is currently not funded.

March 27: Two updates regarding US 30:

• Gary Stevenson pointed out that the four-lane segment that opened in 1964 did not end at the Boone/Story county line as previously listed. Maps and aerial photos from that era showed it ending at what is now 230th Street, with the rest of the four-lane segment opening with the Ames bypass in 1972.
• I have also added the new interchange under construction with County Road R70 east of I-35 to the US 30 central exit list.

February 25:

• Earlier this week, Justin Moore mentioned that County Road F22 markers were recently placed near I-35 earlier this year. While it is well known that Polk County generally doesn't sign its county roads with pentagon markers, I did not mention anything about it on the County Roads of Iowa page until now.
• According to the Nebraska DOT project page for the Lincoln South Beltway, the last two interchanges along NE 2 south of Lincoln opened last fall.

January 7:

• After more than two decades, I have decided to replace the photo on the front page with not one, but two highway scenes: one of a rural highway and one of an urban Interstate. Both of those photos were taken during the summer of 2023.
• I have also reviewed and updated the External Links page, along with any external links on the Freeway Junctions and Photo Gallery index pages.
