A view of the junctions at 16th Street, taken from the Illinois Central tracks, looking west. 16th Street tower is on the right, with the New York Central and Chicago, Rock Island & Pacific lines passing in front and crossing the IC on the level.

On the left is the block hut belonging to the IC railroad, whilst in the background two lift bridges can be seen. These carry the Illinois Central and the Baltimore & Ohio across the Chicago river.

A 152-lever GRS Model 2 interlocking machine, installed in 1901, controls the layout. An additional 48-lever machine was added in 1929 to control crossovers between the NYC and the Rock island tracks at 22nd Street.
