This is about spanning time and space.

In the heart of downtown Toronto, sometimes the most important work happens when everyone else is sleeping.

It takes coordination and planning to get a piece of metal the length of three school buses into – and over- the heart of the city. Done under the cover of darkness to avoid traffic, an oversized load was recently trucked into the city, while dozens of workers stood at the ready to put up a new bridge.

The very heavy piece of steel was recently lifted into place over top of Bay Street – one of Toronto’s busiest streets.

The massive new span was installed by dozens of workers and two massive cranes. It’s 36 metres long and weighs 210 metric tons. When it opens later this year, it will connect the new Union Station Bus Terminal with Scotiabank Arena.

Check out the time-lapse video of the installation here – thanks to our partners at EllisDon.

When it’s done, the new, larger Union Station Bus Terminal will have 14 bus bays and provide more indoor space for GO bus customers. It will be connected to the city’s PATH network, allowing GO and UP Express customers to quickly move between rail and bus, as well as around downtown Toronto.

The construction – which is well underway – is a joint project between Metrolinx and Ivanhoé Cambridge and Hines. The project includes two office towers (81 and 141 Bay Street) and an overbuild park spanning the GO rail corridor, which will be the first of its kind for the city.

The time-lapse video was shot in December 2019, but the video was just released earlier this month.

Since the video was taken, workers have been putting more finishing touches on the bridge. Here’s what it looks like now as it edges closer to opening later this year.
