The Iowa Department of Transportation is having a special September letting. Contracts are accelerated rather than waiting until the normal date later in the month.
Four of the lettings are in Bremer, Polk, Scott, and Story counties. All of them are because a girder on the underside of a bridge got whacked by something. In Polk County, it’s on the I-80 eastbound flyover ramp in the west mixmaster.

The other four lettings are in northwest Iowa for debris removal following the flooding this summer.
