1901 CN/GTW International Bridge over Niagara River and Black Rock Canal at Buffalo, NY

River: (Bridge Hunter; Historic Bridges: Satellite)
Canal: (Satellite)

Technically, I assume the International Bridge is just the part over the river. According to the satellite image, the international border goes through the center pier of the swing span. But I also include the swing span over the Black Rock Canal. I remember this canal from my study of the Peace Bridge down at the mouth of the Niagara River. 

This bridge uses the piers from the original 1873 bridge. Considering the amount of ice Buffalo must see, I continue to be amazed by the strength of cut-stone piers.

There are more spans out-of-frame to the left. This captures both swing spans because we can see the top of the canal span on the right side as well as the river span.

I found a gap in the tree line that allows me to capture most of the spans.

And a gap that gets all of the spans.

And this closeup of a typical span shows it is a pin-connected truss.

Going back to the original tree gap to get a closeup of the swing spans. Evidently the span over the canal is open for marine traffic when the street view car drove by.

This is the span over the canal.

Rather than build a bobtail span, they let the balance span extend out over the road.

The bridge in the background caught my eye.

Brian R Maghran: Would that be the Canadiana there?
Al Filimonow: Brian R Maghran sure is
James Mazur: The Canadiana came back after serving Boblo Island and having her front end damaged by a lift bridge.

This is the International Railway Bridge, which connects Fort Erie, Ontario and Buffalo, NY. It is a through truss bridge with two swing spans that was built in 1901 and carries the Canadian National Stamford Subdivision over the Niagara River. Photo credit belongs to Tom Habak.

The Coast Guard keeps playing a pre-recorded message that the CN RR's Harbor Draw bridge "is stuck in the down position". It says the bridge was expected to be back in service on the 14th. Not much of that makes any sense. I'm guessing they mean the "closed" position since it's a swing bridge & I wonder if the message is stuck on repeat for the last 2 days or if the bridge still isn't fixed.

These closures were not orchestrated by BSA but we were informed by CN (the railroad company) that this is necessary to maintain the active international industrial infrastructure. 
-
From GObike: Hopefully we can get some improvements to the walk/bike crossing, including consistently keeping it open.

[This article verifies that the bridge was owned in 1928 by Grand Trunk Railway, thus the label "rrGTW" for this post.]

When they constructed the 1901 bridge, they used a travelling truss. The travelling falsework was a truss that was bigger than the new trusses, which was bigger than the old trusses. The travelling falsework was built over shallow water using traditional falsework. [eBook

Brian R. Wroblewski posted four photos with the comment: "I was out to catch a tug-barge unit this morning in the Black Rock Canal in Buffalo & ended up under the CN RR Harbor Draw swing bridge on the bike path. Here's a few detail shots of the bridge's locking mechanism on the East side of the canal. It was originally built in 1916 & still operates."
