Preparing for Iowa’s transportation future means understanding not only the present and future needs but also studying the past. At the Iowa Department of Transportation, our environmental unit within the Office of Location and Environment is staffed by experts in wetlands, endangered species, air quality, traffic noise/vibration, regulated materials, and historical and cultural resources.
Iowa has about 9,400 miles of state-managed roads and 4,100 bridges under our care. Many of these roads and bridges were built decades ago and are in need of repair and updating to meet the transportation needs of today and into the future. When a need is identified, our engineers study many options to solve the problem. They prepare alternatives that are studied from many angles, one of which is the impact of the project on the surrounding land.
