LONDON, ONT. -- Cement trucks started to line up on York Street early Tuesday morning for what could be the biggest one-day 'pour' in the city.

Crews are pouring 1,200 cubic metres of concrete in one day for a new highrise building on King Street.

With eight to nine cubic metres in a truck, it was expected to take around 120 trucks to complete the job.

The pour is for a York Development site just west of Richmond Street, between King and York streets.

The 31-floor highrise, across the street from the Covent Garden Market, will have 266 units and is slated to open in three years.

York remained open to traffic, but with the COVID-19 pandemic keeping things quiet, there were few delays.
