Transportation Corridor Improvement Group (TCIG) is made up of member representatives of an existing coalition comprised of the Missouri Department of Transportation (MoDOT), East-West Gateway Council of Governments (EWGCOG) and Metro. Collectively these agencies perform a central role in funding, building, and managing key components of the transportation network in the St. Louis area. Because coordination among these agencies is so critical to the success of any transportation project, a meeting is held each month with the study team and agency representatives to monitor progress and provide insight.
