North Branch of Chicago River died green

I've never seen this angle of Chicago before. I did not realize the North Branch was this curvy. The bridge in the foreground is Belmont Avenue Bridge. The straight river wall in the middle is part of the turning basin.

The North Branch used to have even more curves.

A steam scraper removes topsoil on June 8, 1904, in an area near Addison Street in Chicago, Illinois. The Sanitary District of Chicago (now the MWRD) straightened and enlarged portions of the North Branch of the Chicago River at the beginning of the 20th century to improve drainage and reduce flooding. The original river was a relatively small, curved and meandering stream between Lawrence Avenue and Belmont Avenue. By the end of the project, some portions of the river were widened and deepened, and other areas were filled in and replaced by a completely new channel
