If a view is looking upstream, then we generally see some of the bridges over the St. Marys River.

With only a short break in navigation each year crews both past and present make the most of each day and every opportunity to work on critical equipment. This photo, taken #OTD in 1935 shows the Davis Lock serving as a dry dock allowing for hull inspections and repairs while work is underway on the lock.

I wonder when this last was done.
I think it stopped in the 1960s.
I'm saving a satellite image since it is supposed to change because the second big lock has finally got some fundtion.

It takes a pretty big hole to build what will be longest lock in the world. This 1911 photo shows excavation well underway for what will become the 1,350 foot long Davis Lock in Sault Sainte Marie, Michigan. When it opened in 1914 it was the longest lock in the world.

- MacArthur Lock, 1943: 800' x 80' x 29.5'; this can handle salties, but not Lakers (Video from David Kaye)
- Poe Lock, 1896: 800' x 100'
- Poe Lock Rebuilt, 1968: 1200' x 110' x 32', this is the one the lakers must use. That length and width can also handle a 15-barge tow. But I suspect barges can't risk being on a Great Lake if a storm hits.
- Davis lock, 1914: 1350' x 80' x 23.1'; light freighters, tour boats, and small craft when traffic warrants
- Sabin Lock, 1919: same as Davis but it has been "mothballed."

The replacement of the two unused locks by a $580 million second "laker" lock is on a list of 40 potential U.S. infrastructure "megaprojects." I expected a lot of iron ore and grain to be shipped through the locks, but I was surprised that coal is also shipped. It turns out it is coal from the Wyoming Basin that is transloaded to boats on the west end of Lake Superior. 70% of the freight through the Soo Locks uses the Poe lock.

This photo from this date in 1893 shows men working on the First Poe Lock. Clearly safety requirements were a little different back then. What things do you see that would no longer be allowed?
Anne Boyd Earle No hard hats; no life jackets or tether lines; is that seriously someone walking on the cables of that crane??? OSHA would have a field day with this.
Terry Mitchell Anne Boyd Earle. Your right but I worked for ACE and our Safety is much Harder than OSHA Ours is more strict in addressing situations. For instance take Cranes We have a much more testing before they are Certified. Plus the riggers have to be Certified to rig a load of say palletized material. And We cover Divers. LOL The list goes on and on.
The last ship through the locks in 2019 was on January 15.
First, they have to build a pile of "stop logs" so the gates can also be dry for maintenance. Each log weighs 49 tons.

When the Soo Locks ( Poe Lock) are very busy and you are on a tour boat with a schedule, sometimes you have to share, with a freighter. We had to get in front to avoid prop wash and be first out. Talk about splitting hairs, we passed it in the Lock. With a veteran 30-year tug boat captain, no problem.

Ships wait to enter the Poe Lock during summer 2015 during a traffic backup caused by unexpected repairs to the MacArthur Lock.
"The Soo Locks can’t accommodate 1,000-foot freighters today, Sept. 10, [2019,] since its largest lock is out of commission for emergency repairs. This is the second quick fix on the Poe Lock in about two weeks, UpNorthLive reports. The closure could cause a backup at the shipping channel....The Poe Lock is scheduled to be closed to navigation in order to complete repairs to the Upstream Gate 1 sill today, September 10, 2019.
The lock is expected to be closed to traffic for approximately 12 hours, beginning at 9am to allow divers to safely make repairs.
Concrete grouting of the sill is required to mitigate the risk of further concrete degradation. A more permanent repair will be made during the winter shut down period when the lock is de-watered."
|U.S. Army Corps of Engineers, Detroit District posted [Dec 17, 2019]|
The MacArthur Lock in Sault Ste. Marie, Michigan closed for the season on December 15. Critical repairs began immediately, including replacing gears that operate the lower gates and performing electrical system upgrades.
The Poe Lock will be open to vessel traffic through January 15. Once closed, the Poe Lock will be dewatered for work on the gates, sills, emptying valves and cleaning the drainage system. Teams will conduct a thorough inspection to ensure safety and reliability.
All work is scheduled to be complete before March 25, when the 2020 navigation season begins.

Shortly after the last freighter for the season left the lock, crews moved cranes and barges into the lock to begin setting stop logs (steel bulkheads) at the upper end.
Adam Bertrand US army LT Tug boat
U.S. Army Corps of Engineers, Detroit District It is the USACE Tug Billmaier. This tug normally operates out of the Duluth Area Office but is supporting lock maintenance activities this winter.
Using the new heavy lift crane on a floating platform, eight stop logs are set into place to create a temporary dam at the upper end of the lock. Each log spans the 110 foot wide canal and weighs about 50 tons.
Workers remain in constant contact with the crane operator as the logs are lowered into slots in the lock walls. Crews on both sides of the canal ensure that the logs descend evenly to prevent them from sticking.
After setting the stop logs, the crane moved East in the lock to set a temporary bridge across the Poe Lock.
Don Paton May I ask the weight of temporary bridge? looks heavy.U.S. Army Corps of Engineers, Detroit District The bridge actually weighed more than the stop logs when it was set into place. The bridge was over 60 tons. Probably due to its width and the reinforcing required for heavy equipment to use it.
Workers help guide the bridge into position. Having temporary bridges across the MacArthur and Poe Locks has allowed more flexible use of heavy equipment during lock maintenance. Without the bridges, all equipment had to be delivered by barge before dewatering the lock and could not be removed or used elsewhere on the facility until spring.
Bob Brickman Is this a ‘Bailey Bridge’?U.S. Army Corps of Engineers, Detroit District This one is a panel bridge, similar to a Bailey Bridge
The Detroit District Dive Team plays an important role in dewatering the lock. Divers hook up bubbler systems and chink leaks between the stop logs.
With water temperatures around 34 degrees, divers were comfortable working in dry suits but on the surface tenders braved 18 degree air temperatures with the windchill making it feel like 1 degree.
Workers help ease the log into its slot in the lock wall while the signalman tells the crane operator to hoist the load.
Don Paton It’s me again, are these logs stored onsite for use again? Or where they fabricated for this job only??Greg Turner Both. They are stored onsite but additional stoplogs were procured so that the dewatering gate could also be maintained.
[A comment on another photo indicated the stop logs weigh 50 tons apiece.]
As the log is lowered into the water a worker on each side holds a sounding line to monitor the depth of the log. This way even when the log is out of sight they can ensure it is sinking evenly and verify when it has reached bottom.
A view of the installed stop logs at the upper end. At the right the intake ports for the lock are visible. These openings in the lock monolith allow water to flow through the culverts and into the lock chamber.
U.S. Army Corps of Engineers, Detroit District The logs are just over 4 feet high and across the center, where they are widest, are 8.5 feet wide. To span the entire canal and fit within their slots they are 116 feet long (6 feet longer that the width of the canal).

State of the locks
Army Corps of Engineers budgets $75 million toward Soo Locks upgrade $75m struck me as a drop in the bucket (lock?). But a step is better than no steps since 1986 when the new lock was authorized. "If Congress appropriated the requested $75.3 million for the project next fiscal year, it would keep the project on track for completion seven to 10 years from whenever construction starts, said Lt. Col. Greg Turner, district engineer for the Army Corps' Detroit District."
The U.S. Army Corps of Engineers is proposing a second full-size lock for the complex at Sault Ste. Marie. It would cost about $1 billion. Officials say the proposed 2020 funding would pay to begin construction of upstream approach walls, continue design of the lock chamber and finish upstream channel deepening. Lt. Col. Greg Turner says it would keep the project on track for completion in seven to 10 years. [ClickOnDetroit]

Arthur M. Anderson makes an icy passage downbound at the Soo. This undated photo is from my collection of old prints. From the appearance it could be winter or spring -- around Lake Superior those seasons often look alike. I'm guessing it's spring, so appropriate for today.
Richard Wicklund: The Anderson is in the MacArthur Lock by the viewing stand on the left, which means this picture was taken before its lengthening in 1975. The USS circle below the name was applied to Tin Stackers in the late 1950's, so this could be a 1960's or early 1970's photo.
Al Miller: Richard Wicklund Good points. I can just make out the International Bridge in the background, so that would push it into the '60s.
