Message from Iowa DOT Director
Paul Trombino III

Paul Trombino III Welcome to the Iowa Department of Transportation where a professional workforce of nearly 3,000 individuals is dedicated to moving people and goods efficiently, effectively and safely.

Iowa’s multimodal transportation system is unique, in part because of our state’s geographical location at the center of the nation. Iowa serves as a crossroads for our country’s surface transportation system, with transcontinental Interstate highways 35 and 80 traversing the state and meeting in Des Moines.

The country’s busiest freight rail system crosses Iowa’s midsection and the nation’s transcontinental passenger rail service (Amtrak) currently traverses the southern tier of counties in the state.

Iowa is also the home of the Des Moines International Airport and seven other commercial service airports, connecting our state to the world. In addition, there are 101 general aviation airports in Iowa, as well as 125 private-use heliports.

There are 35 public transit systems in Iowa, including 19 in urbanized areas and 16 serving regional areas of the state.  Iowa is one of a few states with public transit service in every county.

We are also the only state in the country bordered by two navigable waterways – the Missouri and Mississippi rivers.  The Missouri River, which is about 2,540 miles long, is the longest river in the United States. The Mississippi River is the second largest river in the country, an estimated 2,348 miles long.  Both rivers provide tremendous economic and recreational value to the state.

If you enjoy off-road transportation, check out the more than 1,400 miles of multi-use trails and off-road paths designed to accommodate bicycle and pedestrian traffic.

Because of our state’s centralized location, and resulting economic thoroughfare for domestic and international travel, there is a tremendous demand on our state’s transportation infrastructure.  The Iowa DOT has a long history of meeting this demand by continually making improvements, prioritizing safety and mobility, to deliver a great transportation system.  The near future presents many opportunities for all Iowans to provide input into the transportation system decision process.  Investments in transportation secure our economic future and vitality.  We look forward to working with Iowans in the coming years as we deliver a diverse and modern transportation system.

Quality customer service is a critical value for us and your feedback is important.  As you review our website, please provide us any feedback regarding your information needs.  Thank you and safe travels.
