It wouldn't be a long weekend in the 6ix without some kind of construction project. This Labour Day weekend, the disruption will come around Union Station due to the installation of a new Bay Street bridge. Toronto will see the new glass pedestrian bridge will link Scotiabank Arena and the under-construction Union Station Bus Terminal.

Metrolinx warns that downtown commuters and walkers should be aware that Bay Street will be closed between Front Street and Lake Shore Boulevard - the stretch that runs underneath the Gardiner adjacent to Union - from 12:01 a.m. tomorrow, Aug. 31, until 5 a.m. on Labour Day Monday, Sept. 2.

As a result, GO customers will have restricted access to both the Bay East and Bay West walkways, and it's also warned that GO buses may experience delays.

Impressively, the bridge is set to be completed in just two weekends of work.

"On the first weekend, we'll set up cranes and shoring towers – the bridge will then be lifted in two pieces," Grant Bailie, director of Rail Corridor Infrastructure at Union Station, explained. Bailie adds that on the second weekend, crews will install storm pipes and drains, insulation, a vapour barrier, and metal cladding.

Once completed, the new raised bridge will ultimately allow GO commuters to safely cross Bay Street above traffic and directly access the new bus terminal. It will also serve as an extension of Toronto's PATH network, protecting pedestrians from severe weather conditions.

This weekend's construction is the latest phase of the masterplan to establish a revamped GO Transit Union Bus Station at the new CIBC Square at 81 Bay St.

"This pedestrian bridge is an important part of the new Union Station Bus Terminal project," Bailie says. "Seeing this piece and the rest of CIBC Square rise from the ground is extremely satisfying."

If you're going to have to face the disruption because of your long weekend plans, there is some good news! Metrolinx officers will be on-site throughout the closure at both Front Street and Lake Shore to offer assistance.
