Chicago Railroads - Vertical Lift Bridge II
In Illinois, United States
How Geocaching Works
A film can
Look to the south and you will see...
There is a trio of these bridges and only one is in operation. While I was placing the cache the bridge did raise to allow a boat to pass underneath. Cool!
The vertical lift bridge has a tower at each end of its span. Cables attached to ends of the span pass over pulleys at the top of the towers and are fastened to counterweights that equal the weight of the span. The span moves up and down like an elevator.
Big and beautiful. :) Also notice the structure that is the Chicago Skyway in the background. An engineering marvel in it's own right.
To the north there is a smaller and less heavy duty version of the same type of bridge.
Vertical Lift Bridge Heaven!!!
A BIG bit of trivia? The Blues Brothers jumped this bridge in the movie. Catch the clip here...
