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.  |
