Division Street Bridges over I&M Canal, Des Plaines River and CS&SC at Lockport, IL

DPR Bridge, 1899: (Bridge Hunter; Historic Bridges3D Satellite)
CS&SC Bridge, 1905-1993: (Bridge Hunter; HAER; Satellite, gone)
I&M Canal Bridge: (Bridge Hunter; 3D Satellite)

CS&SC = Chicago Sanitary & Ship Canal

When I first came to the Chicagoland area, I not only drove Division Street from State Street in Lockport to IL-53, I went south on an access road along the SC&CS to visit the Lockport Lock. Now Division Street is closed to the public between Praire Avenue in Lockport and the Lockport Prairie Nature Preserve. This is what you encounter when you head east along Division Street in the preserve.

Jeremy Brzycki got a better view past the trees of the trusses over the DuPage River.

Ben Felber Wow alot to dial for an emergency....911 would be quicker.
Josh Anders Ben Felber and 911 would have to call one of them numbers to open a Damn or somthing. 911 wouldn't be much help there unless people where under water already.
Adam J. Bader Sr. What causes the water flows?
Dennis DeBruler A sudden change would be caused by these control gates being opened to lower the level of the water in the Chicago Sanitary and Ship Canal.,-88.../data=!3m1!1e3
I don't know when the last time was that they were opened.

West Division Street Lockport Illinois

It takes more guts than I have to go down the access road along the west side of the CS&SC canal to get to here to take the above photo. I chicken out when I encounter the gates across the access road.

The top photo in eBook has a 1948 view of the three truss spans.

The Bridge Hunter page for this multiple-truss bridge has several photos by three people. They recognized the historic significance of these pin-connected trusses.

The bobtail bridge that used to go over the canal is similar to the 135th Street Bridge that has been preserved in a Forest Preserve.

GENERAL VIEW OF THE BRIDGE IN OPERATION - Lockport Historic District, Chicago Sanitary & Ship Canal, Swing Bridge, Sixteenth Street, Lockport, Will County, IL

There is something wrong with the view above because the view below looks more appropriate. Is the canal partially drained above so that they could do work on the bridge? Both views have the 9th Street Bridge in the background, so they are both looking North.

This is the view I would expect to see for the bridge in operation.

This old aerial view shows that there was a jog in Division Street to accommodate the bridges.

Was the 1939 photo taken during a drought? The river is significantly narrower than today's river.

Even the plain bridge over the I&M canal has changed since I first came to the Chicago area. In fact, this one changed since I started writing this blog in May 2014. On one of my trips to check out Lock #1, I noticed that Division Street was closed over the canal. Below is the old bridge. You can see the steel I-beams that were added under the deck as a "patch" to prolong its life.
