MidAmerica St. Louis Airport MetroLink Extension

The 5.2-mile MetroLink extension from the Shiloh-Scott Transit Center to MidAmerica St. Louis Airport will further expand the region’s safe, integrated public transit system. It will feature a new MetroLink station at 9660 Airport Boulevard, Mascoutah, IL 62258, directly across from the passenger terminal, improved roadway links providing more direct access to MidAmerica St. Louis Airport, and a 5-mile expansion of St. Clair County Transit’s ever-evolving MetroBikeLink System of trails.

Fueled by significant investment from the State of Illinois and St. Clair County Transit District, the project strengthens mobility, supports economic growth and enhances multimodal travel options for residents, visitors and future generations. It will position the transit system as one of the only in the country to connect two major airports with the MetroLink running approximately 43 miles from St. Louis Lambert International Airport to MidAmerica St. Louis Airport.

More details will soon be made available.
