The Iowa DOT is studying Interstate 380 in Iowa from U.S. 30 in Cedar Rapids to north of I-80 in an effort to increase mobility across the interstate system. This study will follow the planning environmental linkages (PEL) model, also referred to as “Planning Study,” allowing the department to make system-level decisions that will help shape individual projects throughout the corridor as they are developed and constructed over time.
It is critical to identify important resources within the corridor early in the process to allow time to develop potential solutions that avoid, minimize, or mitigate impacts to these resources. The PEL will evaluate the safety, capacity, infrastructure, and other topics regarding I-380. These are documented in a series of technical memorandums.
Public participation is an important component of this process as it gives an opportunity for interested individuals to help identify these resources, as well as share what is important to them. It also serves as an opportunity for the Iowa Department of Transportation to keep the public informed and provide feedback on potential improvement strategies as they are refined. The comments and opinions submitted will be used to help make informed decisions throughout the process.

Study Area Map
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.
