The Transportation Improvement Program (TIP) is the mechanism by which federal, state and local funds are approved for all significant surface transportation projects and programs in the region. The FY 2024-2027 TIP comprises the first four years of the 2050 Metropolitan Transportation Plan (MTP) for the Atlanta region, both of which are adopted in February 2024. As the federally recognized Metropolitan Planning Organization (MPO) for a 20-county region, ARC is responsible for developing and amending/updating the TIP and MTP to meet federal planning requirements and address local needs.
All amendments require a conformity determination from the US DOT, in consultation with the US Environmental Protection Agency (EPA). The most recent conformity determination was issued by US DOT and US EPA on May 23, 2025.
Through staff analysis and the interagency consultation process, the changes proposed by Amendment 5 were found to have no impact to the region’s air quality conformity status or the fiscal constraint of the ARC MTP and 2024-2027 TIP. These findings will be formally documented in Volume III: Conformity Determination Report of the MTP/TIP document set following final approval of the amendment in December 2025.
