He must not have tried very hard, it's been in the newspaper since 2013 since they've been arguing about putting in a traffic signal and over cross driveway access. As others have said, they are not really going to fully connect the parcels or get to 5th since TX Roadhouse and the auto store were not designed to do that.
Assume signal will be at Walmart entrance, and help the joke of a "no left turn" at the Walmart driveway by Wendy's south of 5th.

I agree with many others about the frontage road needs, but they have the same problem in Ames on Duff as in Ankeny on Delaware...Either you can't put one in b/c of ex parking lots, or the parcels are not deep enough relative to the the frontage road far enough away from the main road to store the departing vehicles.
