The RPA-18 is comprised of a network of roads, trails, transit, barge and rail facilities that allow people and goods to move within and through the area. These systems provide the basis of a multi-modal transportation system to be built upon and expanded, as needed, to fulfill the vision of the RPA-18.

Identifying the needs of a multimodal transportation system over a long period of time is a required step in maintaining and expanding the transportation system to accommodate current and future needs. This document serves as a framework for addressing these needs and achieving a transportation system that is functional, safe and efficient.

The Iowa Department of Transportation (Iowa DOT) organized the state into 18 Regional Planning Affiliations (RPAs) to provide long range transportation planning on a regional level. Each of these 18 RPAs is responsible for developing a long range transportation plan (LRTP) for its member counties. The LRTP will foster a coordinated effort within the region to provide an efficient transportation system and promote interlocal cooperation.
