All physical assets, such as bridges, culverts, embankments, paving and traffic controls, continually deteriorate, requiring that a certain percentage thereof be renewed every year. In addition, the opening of a new plant or relocation of a state highway can create the need to upgrade roads to accommodate new traffic. Thus, county road departments, along with all other road agencies, have a constant need to identify upcoming needs, initiate projects, conduct surveys, perform design work, let contracts, and inspect new work as it is built.
To accomplish this, each county maintains engineering staff and tasks them with the job of selecting, preparing and administrating construction projects. This work flows in the following sequence:
Iowa county road departments always have a sequence of future projects "in the hopper". By law, they are listed in both a "County Five Year Program"; and a Federal aid "Transportation Improvement Program". These project lists are updated and reapproved annually by the County's Board of Supervisors, the Iowa DOT and the FHWA.
The following summary gives an overview of the number, extent and projected costs of projects planned in the latest road programming.
Contact your local county engineer to find out more about the projects planned for your county.
