AIR QUALITY

Northern Ada County FY2006-2010 Transportation Improvement Program (TIP) Conformity Amendment
In March of 2006, the Idaho Transportation Department (ITD) received the authority from the Idaho Legislature to bond $200 million as part of the Connecting Idaho (GARVEE) program. As a result, ITD is requesting the FY2006-2010 Northern Ada County TIP be amended to include a widening project on Interstate 84 between the Garrity Road and Meridian Road interchanges. ITD's request triggers the need to re-demonstrate air quality conformity. This document fulfills that need.
