Can you help identifying this bridge?
The title said Ghost River Bridge 1927. But the structure and river level confused me. I did not recognize it. Our go-to Cochrane resident, Gordon Davies, also came up with no answer.
I first thought this is a railway bridge which sent me down the wrong path for quite a while.
In 2024 we published this photo which looked suspiciously familiar.
Notice the water level is very different.
I used Google Earth for an aerial view. That confirmed what I thought I already knew. No such bridge currently exists.
Eventually, I thought about a trip out to the dam to investigate.
I took some pictures and video from the parking lot at the Ghost Dam Reservoir. I thought I may be able to match the hills in the background.
Then I saw this. The concrete pilings looked very familiar. The bridge length didn’t seem right, but the shape of those pilings was spot on.
The photo from Glenbow clearly shows the location of the old bridge from the Dam construction site.
Then I typed a poorly formed prompt into ChatGPT and got the answer below.
Here’s what’s known about it:
It was constructed as part of infrastructure development around the creation of the Ghost Lake Dam and reservoir in the late 1920s.
The bridge used a Pratt truss design typical of late-19th and early-20th-century engineering, and it was built between 1927 and 1928 — exactly when your image notes the construction taking place.
It carried traffic over the Ghost River near the future site of the reservoir, before the lake filled following dam completion in 1929.
Unfortunately, the original structure no longer exists in that form today (later replacements and highway realignments have removed or obscured many early bridge remnants), but historians and local heritage groups recognize the photograph as representing that early Ghost River crossing near Ghost Lake.
I believe this information came from the summer village, Cottage Club.
