How the FIVE-way stop in Waukee hasn't been mentioned is beyond me. Its next to the high school and two middle schools, and has backups somewhere like 20 cars deep (not an exaggeration either). Can't stand it as I live so close to it that I pretty much have to use it to get to/from home.
I've heard rumors of a project to cut Northview off of that intersection and making it a 4 way stop. Still, even then I think they'll need to add a stop light because surely it will still get very backed up.
