Oops, I sat on this so long it hatched!
Months ago, while perusing the Iowa DOT’s document archive, I came across a project in Traer that had not been done yet. The contracting date was last September, and work has just begun.
Up and down US 63, the sidewalk corners are being reconstructed to meet Americans with Disabilities Act requirements. (In some cases, they are being reconstructed again after recent construction.)
This relatively minor project, which still clocks in at 39 pages with details for every curb, includes closing the outer lanes of traffic on 63 while the work goes on.
