The addition of a flyover ramp from northbound I-35/80 to IA 141 and two ramps to/from Meredith Drive are the subjects of a DOT meeting March 9 in Urbandale. Three maps and two HD animated renderings are at the PIM site. (The animations are very large.)
The most interesting part of the animations may be the signs at the beginnings and ends. There’s a giant BGS at the two-lane exit to the flyover, with through traffic for I-35/80 marked with upward-pointing arrows (a very stupid MUTCD change) and Minneapolis/Chicago listed instead of Minneapolis/Davenport. West/southbound, it starts at the future 100th Street exit and goes nearly all the way to Douglas Avenue, where there’s a sign that says “80 West / Omaha” at the very end, not including Council Bluffs.
