What is the purpose of an IAMP? An IAMP is a long-range (20+ year) plan and agreement developed to protect interchange function and operations, manage land use and transportation decisions in the IAMP area, and balance local and regional access and travel needs.

Why an IAMP? An IAMP offers the opportunity to think proactively about the future of an interchange. For the I-5 interchange at Chemawa Road, the IAMP process will bring staff, citizens and elected officials from Keizer, Salem and Marion County together to discuss future plans for the area and cooperatively agree on the best ways to manage the movement of traffic, goods and people through the interchange.
