More than 2250 cubic metres of concrete was poured in just over 24 hours as the next phase of the Toronto-York Spadina subway expansion at the Vaughan Metropolitan Centre Station site.

The massive pour by St. Mary’s CMB, was to fill the main entrance ring for the station. Because of the magnitude of the pour, two concrete plants, with a third on standby, were required to produce the concrete, according to information posted by the TTC.

At 3:30 a.m. on Saturday, July 4, 2015 the concrete pour began. Concrete trucks arrived every five minutes and construction crews worked in 10 hour shifts, with two crews placing the concrete in different sections. Concrete was placed at a rate of 70-100 cubic metres per hour with a total of 2250 cubic metres poured. The great big pour finished 24 and a half hours later.

The Toronto-York Spadina Subway Extension Project will provide an 8.6 km of tunnel and track, extening the existing TTC subway system across the municipal boundary between the City of Toronto and The Regional Municipality of York (York Region). The project includes the construction of six stations along the route and the building of parking lots to accomodate 2900 cars daily.

The $2.6 billion project is being funded by federal, provincial and municipal levels of government and is scheduled to be completed in 2018.
