Bridge demolition

VIDEO: The Bloor Street West rail bridge demolition

Construction on the Davenport Diamond Guideway project plows ahead with a recent demolition.

Dec 21, 2020

Think of this as a bit of a ‘time span’. Recently, crews took down half the Bloor Street West rail bridge, installed safety railing and restored the road in just one night.

And we’ve managed to get a rare vantage point on the quick work, thanks to a time-lapse video that compresses it down into about 50 seconds.

It’s all part of the Davenport Diamond Guideway project, which supports future two-way, all-day train service on the Barrie line.

At the start of the work, to make sure it was performed safely, fall restraints and harnesses were used as workers needed to approach the leading edge. Of course, there was pre and post demo work to be done. Since only half the bridge was being demolished, and there’s an active rail line on top, the remaining half needed a little TLC.

Prior to the demolition, Soncin Construction added bracings on the east columns for additional support and put in place a track protection system that retains the ballast above. Then on demolition night, York Demolition came in and took down half the bridge structure. Following that, Soncin was there to immediately install the safety railing.

Talk about good connections.

For now, GO trains will continue to travel on the east side of the bridge. Once the west half is built back up and new track is installed, GO Transit will move the trains over and do it all over again on the east half of the bridge.
