CN/WC+DSS&A Bridges over St. Marys River between Sault Ste. Maries

(Bridge Hunter, Satellite)

Street View
(Update: A video of the Roger Blough passing the West Pier under this bridge. I'm learning it is an older boat because it has the bridge and crew quarters on the bow instead of the stern and because it does not have a self-unloader. There is also quite a bit of ice in the canal.)

From Michigan to Ontario, the International Bridge consists of a lift bridge for Locks 1 and 2, a dual-leaf Strauss Bascule for Locks 3 and 4, and a swing bridge over the Canadian lock. The four American locks are known collectively as the Soo Locks.

Before I do the individual bridges, here is a nice overview.

CN Railway Swing Bridge. Sault Marie Marie, Ontario Canada.
This swing bridge has been in operation since 1895 to span the Canadian shipping canal and link the railway to the United States on the south side of St. Marys River.
James Yarduk: Still active. They replaced the main support beams under the railbed about 4 years ago and upgraded the control system. In operation every day during canal season. They leave it in place across the canal in the winter months.
[James provided a 3:12 video of it closing in a comment.]

Roger Riblett shared three photos by James Yarduk.

Joe Granger posted 23 pictures of the Canadian side with the comment:
A few more high quality photos of some of the spans at the International Bridge between Sault Ste. Marie, Michigan and Sault Ste. Marie, Ontario. The swing span and trusses are from 1888, built jointly by the Soo Line, DSS&A and Canadian Pacific. The Bascule Bridge, the largest ever built, is from 1919, and the lift bridge was built in 1954 to replace another swing span. The red swing bridge is the last surviving emergency swing dam and still is swung twice a year. The bridge is now owned by CN. The bascule span is not opened anymore as the 3 and 4th lock are currently closed until a new lock is built.....whenever congress approves the funding. The project was approved decades ago, but they haven't released the funding. 
Twice a day the bridges are closed for a train 
More postings by Joe: an Oopsie Doodles with the lift span, after an accident with the bascule bridge, one leaf of the bascule being raised., all three movable spans, a video of the lift closing for a train then going back up for a boat, includes some detailed shots of the swing bridges gearing and lock pin, and a set that includes some downstream views of the dam, 9 photos of the swing bridge

This rare 'Double Leaf Heel Trunnion Bridge' was built by the Strauss Bascule Bridge Company for the Canadian Pacific Railway in 1919. It was the longest bridge of its kind in the world at 336 feet. The crossing spanned the U.S. Ship Canal in Sault Ste. Marie, Michigan.

Sault Ste Marie Michigan. Taken today [6-24-2017] during the bridge walk. Worlds largest draw bridge. Former Soo Line now CN
Joe Granger posted 16 photos with the comment:
Scanning old photos. Most from 97. The bascule is the largest ever built. Sault Ste. Marie, Michigan. Former Soo and DSS&A.
The entire bridge has a swing, double bascule and a lift span, as well as 9 trusses.
Bill Wischer Actually, it's a double Strauss heal trunnion bridge, which is quite rare- there's one in Sweden crossing a canal as well. Strauss designed 100 bridges- the last of which is the Golden Gate Bridge.

Building the new Soo Line lift bridge at the Soo piggyback on the old swing span.

One of two massive counterweights on the worlds largest bascule bridge. Soo Line DSS&A and CP jointly built. Now CN. Sault Ste. Marie, Michigan to Sault Ste. Marie, Ontario.
Joe Granger posted nine photos with the comment:
1888 trusses, 1911 Bascule and 1954 lift span. Taken by a friend from a 1000’ freighter having just come through the Soo Locks and passing into Lake Superior.
Originally built by the Soo Line and Canadian Pacific jointly, there’s also a swing span out of frame on the 2 mile long series of bridges between Sault Ste Marie, Michigan and Sault Ste Marie, Ontario.
The bascule bridge is 338’ long and the largest bascule bridge ever built.

Dennis DeBruler So they closed the road bridge to traffic so pedestrians could use it? What an opportunity to take photos.
Joe Granger Dennis DeBruler this was the bridge walk. Once a year. [The photo was taken in June.]

Jimmy Polnick: Hey that's the Sault internation train bridge! That's my backyard lol there is like 5 different types of bridge in that span. A lift, a bascule, a swing, a plate girder over pass and 9 camelback spans. It was built in like 1893 or so. At one point it was 2 swing bridges, a plate girder overpass and 13 or so camelback a but the expansion of the Sault locks resulted in one swing bridge (on USA side) to get replaced by a vertical lift bridge. They actually built the vertical on-top of the swing bridge so the amount of time it was down would be minimized.

(new window)  A video making me appreciate the draw bridges around here are a lot faster.
"Built in 1919 , this 339’ behemoth still holds the world record for largest draw span. It is one of several spans on the International Railroad Bridge between Sault Ste. Marie, Michigan and Sault Ste. Marie, Ontario. It was jointly built by the Soo Line, Duluth South Sore & Atlantic, and the Canadian Pacific"



Joe Granger posted 6 closeups of the two US RR bridges with the comment: "Some photos of the 1945 Art Deco-ish machinery house and the worlds largest draw bridge (1913) at Sault Ste. Marie"

David Kayne posted 10 photos of a BNSF train crossing the bridges on 3-19-19.

A video of a train crossing the bridge. The train appears are 0:30.

17 drone photos with the bridges up and down   and a video of the bascule going down   The video includes a couple of USACE dredgers working on the canal to the new lock. In this case, the dredgers are excavators working from barges. In the background, a downbound is leaving the Poe Lock while an upbound is waiting by the wall. An upbound sat in the MacArthur Lock for the entire duration of the video.
