Shows lots of rails on the south side of the river--some on the north side too.

That's actually the Wrigley building that stands out.  The Tribune Tower would be built three years later.

Interesting that a swing bridge was still in use for Rush Street.  That center island would have been an obstruction to river traffic.

The tracks in the lower foreground belonged to the Illinois Central.  Now it's all covered over by the 1960s era Illinois Center office buildings built on IC Industries air rights.
