Idaho 16, I-84 to Idaho 44 Environmental Study

Project Facts

Project Number: A009(963)
Key Number: 09963

The Idaho Transportation Department (ITD) studied options for a corridor between I-84 and the junction of Idaho 44 and Idaho 16 for a potential new roadway. As western Ada and eastern Canyon counties develop, the ability to move north-south traffic is a primary concern. The project will provide a vital north-south link in the Treasure Valley.


This corridor study has been guided by local entities that have authority over transportation and land-use decisions.  The public has had a major role throughout the process.  The ITD Corridor Planning Guide, ITD Public Involvement Guidebook and the ITD Context-Sensitive Solutions Guidebook were used to set the standards for this study.  ITD and the Federal Highway Administration made the ultimate improvement decisions.

In 2001, the Community Planning Association of Southwest Idaho (COMPASS) and ITD completed a cooperative planning effort called the I-84 Corridor Study. The study examined the transportation system needs for the I-84 corridor from the WYE Interchange to Idaho 44 west of Caldwell.

The study recommended specific improvements that warranted further evaluation. The extension of Idaho 16 was one of those improvements.


The Record of Decision (ROD) was approved by FHWA on April 14, 2011.
