Originally built as part of the Pennsylvania Railroad system, this Waddell and Harrington vertical lift span is the only one of its kind across the Chicago River. Upon its completion in 1915, it had the heaviest (1,500 ton) main span of any vertical lift bridge in the United States.
Also called Canal Street Railroad Bridge

In the late 80’s early 90’s I was an engineer at a smelting plant that was located adjacent to the bridge, the sailboats in the back ground are harbored on former site. During the spring and fall boat runs, when the boats would be moved between winter storage and the harbors, we would grab lunch and climb the stairs to the roof to watch. The roof of the plant was close to 100 feet, we would wave to the operator in the control shack. There was always a surprised look on their face. Love that you were also able to catch Amtrak on its way into Union Station. Thank you for posting.
Thank you for your comment. This is a favorite site of mine. I will be returning with my drone for a view at 100 ft myself soon.
I grew up in the Pilsen neighborhood.. as kids we'd go to watch this bridge in action lots of fun ! Times were much simpler in those days !!! Go Sox !
Man vertical lift bridges are such a unique piece of engineering. It’s amazing how counterweights can suspend like that. Where’s the legendary construction workers at? I’d like to hear a back story behind engineering one of these
Those towers aren't your typical towers for a loft bridge. Really cool design concept. Should check out Steel bridge of Portland Oregon. That bridge is the most unique bridge ever to me
This bridge has become something of a Chicago landmark. It shows up frequently in some of the grittier scenes of the TV drama "Chicago PD".
Simply impressive. I love the old siren, I used to remember the ambulance sirens back in the early 70's, they had a cool sound, the siren of today suck and have no b***s.
The 4 chains hooked to the crossmember of the tower and to the bottom of the counterweight on each end add or subtract the weight of the cables as the bridge is raised or lowered. As the bridge moves, the cables also move and change the weight of the bridge so to keep the weight even the chains do that. This is called a bridge on a skew or angle with the waterway as it crosses close to 45 degrees. It is most desirable to build a bridge at 90 degrees to the crossing for ease of construction and design as it will provide the shortest span needed. Most movable bridges are opened for river traffic on an as needed basis unless the train traffic is so intermittent that it is easier to close for train traffic as needed. Most of these type bridges have been fitted with remote controls so the dispatching office can operate them without a bridge tender having to be on location at all times. The bridges which are usually open unless a train needs to use it are operated by controls at the bridge whether it be by electricity, manual, or engine.
Thank you this detailed information. We plan to be taking more drone footage of this bridge in the next few weeks
@@dogstar7 ua-cam.com/video/FGOIOQAgCcY/v-deo.html From this video and it's drawing of this bridge, there are 4 cable spools which take up cables that do the raising of the bridge. They are at the corners of the machinery house under the porches at the sides of the part that extends to the sides of the span. In the drawing you can see the lines for the cables anchored to the tower tops and go down and under pulleys attached to the span on each side of each end before going over and winding on the spools. Since the bridge is adjusted for balance, there is very little load on these cables and there isn't need for extremely large motor or motors. When you do fly a drone look for these cables.
Great find
Love this bridge. It's like the Boonville Katy RR Bridge built in 1932.
I'd love to see the control room view one day very neat bridge
could do with a lick of paint!
very similiar to the newport bridge in Middlebrough UK
😎 Sweet!!!
Used to cross one of these everyday in Belle Chasse Louisiana.
Cool! Vertical lifts are the best IMHO
Hey that's a pretty kick ass video!
Thanks. That way first attempt getting the whole process in one take. This spring I hope to get aerial shots with a drone
Love verticle lift bridges.
Like , very good video edition. Stay c connected
There's another lift bridge in Cleveland Ohio close to where the Cuyahoga River enters into Lake Erie
I'll look it up on Google maps
Great video, that sure is a neat bridge
Well done video, well done.
Love heavy engineering, though I wish they would paint this bridge.
Yes, me too
It took me a while to figure out the pulley system
The huge counterbalance set over 100 years ago will keep the whole span suspended easily
Just as easily the two huge weights are lifted by a few hundred horsepower electric motor until the cables slack and are locked in place by a friction brake.
A coat of paint would be cheaper than replacing the bridge. How many trains pr day pass over the bridge; it seems like an awful waste to have to raise 1500 tons for a small boat to pass under; do they have a set timetable or isit who gets there first gets through passage?
Very cool video. Been over that very bridge many many times.
i never get tried of running trains over this bridge.
wow this looks pretty neaSCREEEECH
Very sad how Amtrak is always pissing money away, and there trains look like they have been in a Mud-Bog.
Not pissing away money. More like not given any money.
Not he only lift bridge. search for aerial life bridge, Duluth.
that 'house' even serve a purpose anymore?
Yes. It has a flashy light.
That's where the bridge tender works & operates the bridge from.
What's it take to get her up? What do you have to pay, and how far in advance?
TJ Cassidy I imagine that the bridge raises and lowers at set times depending on the train schedule.
It is raised every Wednesday and Saturday in the spring and fall.
Roger Deschner No, that’s the rest of the bridges on the south and main branch, this one is so low that it goes up on demand ( unless there’s a train coming), you call it using the name Amtrack bridge on VHF channel 16. It’s actually controlled from the Amtrack tower a few blocks away.
Sounds like the purge is beginning.
Goes up quick, how about a paint job to finish it off..
That's going to take weeks or a month to paint a lift bridge like that.
porquois une sirene d'avertisement
is iot still in iuse
Yes!
Here is a short video of me running lite power over the Canal St. bridge to the UPRR's Canal St. piggyback yard: ua-cam.com/video/49KzKqw4YqE/v-deo.html
Nice accurate info:
Type Bascule (actually lift.)
Good video otherwise. :)
That is referred to as the Amtrak bridge not the Canal st bridge.
It was Canal Street 60 years before the disaster known as Amtrak was formed.
Jess James My comment was for those who may want to have it raised, the bridge tender answers to Amtrak bridge, if you call the Canal st bridge on the radio your going to be sitting there a long time.
"Amtrack"??? How about 'Amtrak'. It's referred to as the Amtrak 21st Street Bridge by the rails.......
Cool video, If you get a sec. check out my video "NORFOLK TUG EXPRESS" it features my first catch of a SD90mac and a rail "lift" bridge opening for the tugs on the river below... Thanks, Moses...
Rusty as hell on this 12y old video and even on recent google street view it is still ugly... and in fact most of those bridges seem to be in very bad shape.
FAR OUT.
