Road and rail bridge

Built to service the coal mines on the south side of the Red Deer river valley, the East Coulee bridge is an amazing piece of local history. Unusual and rare in design it was used both by trains and vehicular traffic on a common shared roadway. Today, the structure is abandoned but that could change if plans to save it come to fruition.

The rail line using the bridge was a spur track coming off a joint CPR/CNR branch line on the north side of the river at the town of East Coulee, allowing trains to access and service both the Murray Mine (not much left) and the Atlas Mine (now an historical site) on the opposite bank. During boom years train after train left those busy operations via this unique structure. From there the coal, mostly used for domestic heating, travelled to all points in Western Canada and perhaps beyond. With the change over to natural gas the demand for the product slowed. The Murray mine closed in 1959 and the Atlas mine, the last in the Drumheller/Red Deer River valley, followed by 1980s. Near the end the Atlas mine only worked sporadically, usually in winter.

This whole time the bridge did its job, allowing trains to reach the mine, and auto traffic to head south (and miners I assume heading for work). Since the addition of a new road bridge further east, the old bridge was closed to all traffic and has since fallen into disrepair. Even so and in spite of how bad it looks, the basic structure seems pretty solid – not that I am a bridge engineer. I am certain if caught in time it could be saved and fixed up. It’s very historically significant and could be easily incorporated into the Atlas mine complex nearby.

I have not been able to find exactly when the bridge was built but I was told anywhere from the 1930s to 1948. I could not find a date stamp in the concrete – bridge builders often include one – but none was found by this author. Regardless of the exact year within that time span, the use of wood construction seems odd. At this later date one would assume steel would be used. The design certainly makes it look much older than it is.

There is a guard house on the north (town) side of the bridge and I assume this person’s job was to block vehicular traffic when a train was due.

Warning, much of the deck planking is rotting away and is dangerous. Do not venture out on the bridge.

The images at the bottom of this report are compliments of and copyright Larry Buchan and show scenes around the bridge near the time the last mine was operating. Larry was employed with the CPR and in the 1970s spent time in the valley working wayfreights (local milk-stop type trains) up and down the line.

He send me this fascinating tidbit about the bridge…

“I remember towards the end of operation using this bridge, came in the late 1970s, we had joint rights with the CNR as far as switching the Atlas Mine was concerned, we would do it for six months of the year, and CNR would do it the other six months, they would come down with big power and were not supposed to go over the bridge with more than one unit, evidently one week they were in a hurry to get over to the mine and out of East Coulee before their train orders expired, so they went over to the mine with three locomotives, this made the bridge unsafe for locomotives to go over, I made one last trip down there in the spring of 1979 when I was taking my locomotive engineers training, so at that time the mine would run the loads down onto the bridge controlling them with handbrakes, we would then picked them off the bridge using other boxcars as reachers if we had to. The mine soon stopped operation not long after this.”

BIG Update: December 2012. I have stumbled across more information about the bridge and the industries it served, some of which clears things up, others that deepen the mystery and some that add a whole new dimension the story.

1) An Alberta Pacific grain elevator used to sit very close to the Atlas Mine, almost within throwing distance. It had its own spur and lasted until about 1980 before being torn down, although it’s believed that rail service to it had ended sometime earlier. This author has seen a picture from the mid 1970s and the structure looks disused and the spur line to it overgrown and rusty. Our friend Larry Buchan who is mentioned further above in this article does not recall ever spotting cars at the elevator. He worked for the CPR in the area in the 1970s and kept meticulous records of his experiences.

2) In the same picture showing the elevator one can spot two coal hoppers siting on the Atlas Mine tracks. This is a odd, as my understanding is that coal from these mines was always shipped in boxcars and any photos I have seen show endless strings of them parked at the mine. Hoppers are never seen except in this one single picture. The output of the mine was mostly domestic heating and cooking coal and it travelled in boxcars since few if any of the coal distributors had facilities to accept bottom dumping hoppers. I guess it’s possible some output was for industrial purposes, which could explain these cars. Although I have heard that Drumheller region coal does not travel well when exposed to the the elements – I guess it breaks down quickly. So, it gets more confusing and this mystery remains.

3) Almost next door to the Atlas Mine was the Monarch Mine, or Western Monarch Mine (I have seen both spellings) and this author has only just found out out it; after my last field visit to the area. This mine lasted until the 1960s making it one of the last to operate in the valley. It too was served by the bridge and had it’s own small yard to feed the tipple. I don’t think there are any bits or pieces of the mine left although I expect some field research is in order to confirm this.

4) In the article above I state the bridge could have been built sometime between the 1930s and 1948. The former now seems likely since I have found a picture of the bridge from 1948 showing it being repaired. One span was skewed and shifted and while it’s assumed that river ice may have done this (given it appears to be spring in the picture), the text that accompanies the picture mentions some damage due to dynamite, without explaining what explosives had to do with it. Dynamite? This invites further research.

5) Seen in that same picture mentioned in the paragraph above is one important fact. In 1948, the bridge was train only and no road decking is seen. So for a period at least, it was just a plain old railway bridge and when the road was added is not know. Again, this invites further research.

6) Into the 1970s, there was sizeable yard, depot and turntable on the north side of the bridge. In one of the pictures supplied by Larry Buchan, one can see the former. On Google Earth a half moon shaped feature can be seen just above the bridge hinting at the location of the turntable. It seems to line up with the picture Larry supplied. Otherwise nothing really remains of the yard.

According to the Atlas of Alberta Railways
The line from Kneehill to East Coulee was completed on June 27, 1929 and the CNR connection at Rosedale was tied in July 20, 1927. The line from East Coulee to Rosemary was opened June 27, 1929.

I love finding “Rare Hidden Gems” like this and I have been trying to connect Hussar, from Rosemary to East Coulee, by way of the Old Railway lines. Have you had a chance to explore any of those lines?

The 1948 dynamiting was to dislodge heavy spring ice that had built up around the piers and the pressure was so great that it was starting to shift the bridge downstream. The plan was to loosen the ice but the resultant explosion shifted the pier instead and the damage you saw was from this botched attempt.


I lived in East Coulee from 1947 to 1959 and I have a lot of memories of the Valley. They must have dynamited the bridge more than once because the one I remember was probably 1952 or 53. I also remember houses floating down the river with the ice. The bridge was out of commission for months until it was rebuilt. There was also another mine on the town side of the river called the Empire. I had family working in all of them My Dad worked in both the old Atlas and he was part of the crew who opened the new Atlas Mine.

Great post, thanks for sharing this blog. That bridge is so fascinating and I must visit it! Thanks again, I’ll be back.
