CHICAGO TRACK ELEVATION

EARLY VIADUCTS

Some of Chicago's earliest grade separations with railroads, consisted of viaducts carrying the streets over the railroads.

Several additional viaducts were constructed over railroads which were later elevated, eliminating the need for the viaducts. These are not listed.
