CPR 1916 Connaught Tunnel Construction

 


Perhaps this article would only be surpassed by the CPR's own records - if one wanted to know exactly how the Connaught Tunnel was built. Although it is quite technical and detailed, it provides valuable insights into the construction techniques used a century ago. 

A tunnel is a work of architecture in which the natural environment provides most of the structure. As often occurs with tunnels, the engineers had to provide supplementary support to the natural features in some areas.

You can picture the 'human experience' of working inside a mountain and travelling to and from work in all seasons of the year. With a bonus system in place for some of the work, the types of risks taken and accidents which might have occurred can also be imagined. 'Tertiary level' hospital care would not been have available to injured workers.

As always, I've tried to work with some of the images in order to better present some of the historical details within the photos and diagrams which people might be interested in.

This article was found as I scrolled along from one of Jim Christie's journal references. That being said, I'm sure (without checking) that he also provided me with the precise links to this reference because he has done a lot of research all through these journals and he certainly would have marked this one!

1917 Construction Details of the Greater Winnipeg Water District Aqueduct, Part 2




 
In the course of his research in preserved professional journals, Jim Christie found a really interesting group of articles detailing the work - over a century ago - on the aqueduct built to supply Winnipeg's municipal water.


Here are the last three articles from the series published in The Contract Record of 1917 detailing this construction. 


The first three articles can be seen at the link below.


I have tried to make the text as readable as possible. In many cases the images have been adjusted to yield more detail and they are repeated in an enlarged form after each particular page of text. The GWWD railway, which runs along the aqueduct, is marked on the 1994 provincial road map below.


































The links to the original journal articles (in copy and paste format) appear below. In some cases, you may need to scroll down to the first page of the article - the number in the link, e.g. 275, indicates the first page. There are also interesting surprises to be found if you choose to scroll beyond these particular articles.
