The bridges at Blue Island

The bridges across the Calumet Sag Channel in Blue Island, Illinois (south of Chicago).

The bridges seen in this image are operated (from left to right) by Iowa Interstate Railroad (IAIS), Indiana Harbor Belt Railroad (IHB), Canadian National Railway (CN, two bridges) and CSX Transportation. CSX operates on the IHB bridge as well. In the opposite direction from this view, Metra's former Rock Island Line crosses all the tracks over a grade-separated right-of-way. The IHB tracks cross the CN tracks to connect to the CSX tracks at this junction, and the IAIS tracks connect to the IHB, CN and Metra lines.
