A few months after Jack helped haul bridge beams to the Donjek River Bridge in Canada, he went back to haul the beams from the staging area off the road onto the ice where they were constructing the bridge. (Best viewed if you click on the first one and scroll to the right.) See captions for more info.
Two cranes are needed to pick up bridge beams, one on each end, since they will break if they are picked up from the middle. In the construction process they are pre-stressed to take weight from the top and won’t hold up if lifted from the middle.
The old bridge is on the left and the cranes are moving down onto the river.
Jack is down on the frozen river here with the new bridge on the left and what looks to him like concrete joints on the right.
The orange tarp is covering the concrete and keeping the warmth in from heaters so that it will cure.
The 2 cranes are on their way up to the staging area where they will pick up the beams and place them onto the trailers for the trucks to bring them down to the river where the cranes will then pick them back up and place them on the bridge in their correct positions.
They are loaded and following the cranes back down to the river.
I am compiling a story on the Donjek River Bridge as my father was stationed at Camp Takhini, Whitehorse with the Royal Canadian Engineers (1952-55) and was part of the crew who built the first bridge. I have some photographs and it’s quite astounding looking at the equipment used back then and the equipment being used on the new bridge. Would I be able to include some of Jack’s photos in my story giving him credit … his is also a GREAT story! Thank-you for your attention. Edith Walker-Mullen. My email: firstname.lastname@example.org
Absolutely Edith! Jack would enjoy looking at your story.
