In November the city said the work 'had begun' and would be broken out into 3 phases.
Phase 1:Water-proofing to make sure that the work that’s happening in the street doesn’t negatively impact the station.
Phase 2: Installation of “anti-terror concrete blocks.” The blocks are crash-rated and are meant to withstand an impact and so the term ‘anti-terror’ is what’s used.
Phase 3: Bollards to be installed all along Front Street West in front of Union Station and at parts of York and Bay streets.
I'm not 100% clear why they need phase 2 as that seems like a temp solution. I guess it is because they need to remove the existing jersey barriers to do phase 1 waterproofing so between that and the actual bollards being installed, they are dropping in some concrete blocks???
