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.
- It was 20 years ago on January 8 when I, a student of the University of Iowa at the time, launched the Iowa Highways Page. A lot has changed since then:
While a lot has changed in the last 20 years, this site will continue to chronicle the evolution of Iowa's highway system. Thank you to everyone who has contributed material to this site.
- This site itself has changed web servers multiple times, adopting the iowahighways.org domain as a redirect in 2004 and as a permanent URL in 2014, while my original photos are now on Flickr.
- Online mapping was relatively new in 1998 while online aerial photos were hard to find until the Iowa Geographical Map Server came along.
- Newsgroups like misc.transport.road have given way to message boards like the AARoads Forum and social media like Facebook (the Mid-America Roads group includes Iowa highway discussion).
- Iowa's highway system has changed a lot in the last 20 years as well — four-lane corridors like the Avenue of the Saints (signed as IA 27 since 2001) and the Des Moines-Burlington Expressway (signed as IA 163 since 2009) were under construction 20 years ago, and a four-lane US 20 from Sioux City to Dubuque, which was unfunded west of Fort Dodge in 1998, will finally be reality by the end of this year.
- When I started this site, research on historic highway alignments was limited to looking at the map collection at the UI Main Library and looking at old newspapers on microfilm. Now, thanks to the efforts of contributors like Jeff Morrison, who's contributed more material to this site than anyone by far, and the increased availability of newspaper archives online (many of which require subscriptions) and historical material from the Iowa DOT's website (including every highway map ever published, going back nearly 100 years), research has become a lot easier.
- Speaking of US 20, Jeff Morrison confirmed from the Iowa DOT that a 3½-mile expressway segment between County Road L25 and the five-lane segment in Correctionville opened last November 22.
- According to the Iowa Transportation Commission meeting notes from December 12, the remainder of IA 192 will be turned over to the city of Council Bluffs in the near future. The listing will be updated once I receive confirmation that signs have been taken down, but I did remove IA 192 from the I-80 west exit list.
- Other exit list updates:
- I-35 south: I added the new interchange with NW 100th Street in Urbandale that is currently under construction.
- I-80 central: Marshalltown has replaced Altoona as a destination at Exit 142, per this story in the Marshalltown Times-Republican.
- I-80 east: Minor signing update at Exit 295A in Davenport.
- IA 141 is now six lanes through Grimes.
