Post Letting Resources

In an effort to expedite the oversight process, the Iowa Department of Transportation (DOT) has tools available for local agencies to utilize in order to provide consistent documentation among the agencies.

Although it is not mandatory to utilize all of the available inspection tools, such use will make the oversight process run more smoothly. However, failure to properly document the progress of these projects may result in loss of federal-aid funding for that project and may jeopardize the utilization of federal funds in future projects.
