This was no small feat of engineering.

Over the past week, a one-block stretch of Broadway between Commercial Drive and North Grandview Highway was closed for 50 hours over three separate occasions to allow for the installation of the street-spanning steel frame for Commercial-Broadway Station’s new pedestrian overpass.

A time lapse video posted by TransLink shows two large cranes were used to raise the frame into position on top of the new pillars.

The additional walkway is part of the $60-million upgrade to improve the station’s capacity and circulation. It provides a new footpath connection between the new fourth platform being constructed for the Expo Line’s inbound direction and the Millennium Line platforms across the street.

To allow for construction, the bus stops for the 9 trolley and 99 B-Line routes have been temporarily relocated to the northwest corner of Commercial Drive and Broadway.

Upgrades to the station are scheduled for a summer 2018 completion.

A number of other Expo Line stations are also receiving upgrades, including Metrotown Station and Surrey Central Station. The first phase of upgrades were recently completed for Joyce-Collingwood Station.
