St. Clair Extension
The St. Clair Extension is an extension for the St. Louis MetroLink light rail system in St. Louis, Missouri and St. Clair County, Illinois, United States.
Proposed route
This extension of the Red Line heads out 5.3 miles northeast to MidAmerica Airport. It is called Phase 3 because it was originally part of the St. Clair County Extension Phase 2 project that extended MetroLink to Shiloh-Scott. It became its own project by the Federal Transit Administration due to low ridership projections. Although design work has been completed, funding for construction has yet to be secured. As of 2010 the plans for the MidAmerica extension have been removed from the Moving Transit Forward's 30-year plan, as they are no longer planning on completing the line since, at that time, MidAmerica served no passenger airlines. However, Allegiant Air resumed service from MidAmerica airport in 2012.
