The map below highlights the Interstate 380 study corridor. The map is interactive; you can pan to a certain location and zoom in to identify the corridor study area. A project study area is the area within which field data is collected to identify all known environmental resources and potential constraints. The study area is established early in the development process and must be established large enough to encompass all potential conceptual project alternatives. For more information regarding the study area, please refer to the Iowa DOT's Office of Location and Environment’s policy 02B021.
Environmental constraints will be included on the map as they become available.
