TIP Amendment

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 2020-2025 TIP comprises the first six years of the Regional Transportation Plan (RTP) for the Atlanta region. As the federally recognized Metropolitan Planning Organization (MPO) for a 20-county region, ARC is responsible for developing and amending/updating the TIP and RTP to meet federal planning requirements and address local needs.

Currently, staff are compiling changes to be considered for an Amendment to the TIP/RTP.

Purpose of the FY 2020-2025 TIP/RTP Amendment #3

  1. Update the travel demand model to reflect the latest scoping changes for projects within the region’s air quality conformity analysis
  2. Edit programming and financial details for Major Mobility Investment Program (MMIP)
  3. Add and remove select projects in the TIP/RTP
  4. Address project cost estimate and programmatic changes that are of a time sensitive nature or cannot be handled administratively.

All amendments require a conformity determination from the US DOT, in consultation with the US Environmental Protection Agency (EPA). This amendment will involve a new air quality conformity determination by the United States Department of Transportation and is expected by November 2021. The most recent regional emissions analysis was approved by FHWA and EPA on March 17, 2021.


Amendment materials are under development and will be linked below ahead of the public comment period.
