Two Lines on MetroLink

The MetroLink network consists of two light rail routes.  The older one, now called the Red Line, has grown to be the nation's longest run, extending more than 37 miles.  From the northwest it goes from Lambert Airport into downtown St. Louis, and then across the Mississippi River.  In Illinois it heads through East St. Louis and other areas southeast to the Shiloh-Scott terminal, far into St. Clair County.  The newer Blue Line runs nine stations on its own southwest of St. Louis from Shrewsbury-Lansdowne I-44 before joining the older route into a closer-in Illinois terminal.

The lines use old railroad tunnels for a mile-long subway under center city. The Mississippi River is crossed on Eads Bridge, which at well over a century old is a landmark in the nation's bridge history.  Part of it shows in this image, taken from the St. Louis side, with an outbound train crossing on the lower level of the structure.
