DUBUQUE, Iowa (KWWL) — Harsh winters often affect road construction deadlines, but the Iowa Department of Transportation says this past winter has not set them back.
“The extremely cold winter with the snow didn’t really affect us because only some bridge work was scheduled over the winter. Now that the frost is out of the ground and the snow is gone, the ground is starting to dry out and our crews are starting to get busy,” says Hugh Holak from the IDOT.
However, it is only April so eastern Iowa is not out of the clear yet in terms of weather conditions. Holak says while the warmer temperatures during the day have allowed crews to get working on the project, the overnight temperatures is what they are monitoring.
“One thing we’re waiting on now is for our night time temperatures to be warm enough that our bridge decks can cure out because once we pave the bridge deck the internal temperature of the concrete has to stay above 50 degrees for seven days.”
Holak says if Dubuque gets a significant amount of rainfall in the next couple of months, this may delay construction of the project.
The road is scheduled to be finished by June of 2020.
