During the fall of 1997 I started putting a highway log together and did extensive research on past highway alignments through old road maps at the U of I’s Main Library. I launched the Iowa Highways Page on January 10, 1998, as part of Jason’s Pad on the Web. Then came Freeway Junctions of the Heartland and the Photo Gallery, which has grown in leaps and bounds since I got my own car in the fall of 1998. As time passed I phased out my non-highway-related pages to focus on what I know. I try to keep up with Iowa’s changing highway system by posting updates in the timeliest manner possible.
How many interstate highways are there in Iowa? Let’s see, there’s I35 and I80 going from border to border through Des Moines. I235 goes through downtown Des Moines. There’s I29 in western Iowa. I380 goes from Coralville to Waterloo. What are we up to, five? Don’t forget I280 in Davenport. Can you think of any more? This table shows ten.
