Metrolinx construction crews will soon begin work to expand Woodbine bridge, leading to a year of traffic disruptions in Toronto's east end.

In a post on its website, the transit agency announced that a new span will be added to the bridge's north side, allowing for a future fourth track that will support more frequent service on the Lakeshore East GO Line.

Scheduled to begin the week of January 16, the three-stage project will impact vehicle, pedestrian, and bike traffic on Woodbine Avenue until next winter.

The first stage of the project will see traffic lanes shift to the outer edge of the road on Woodbine between Danforth Avenue and Gerrard Street East as crews begin work on the centre pier. Bike lanes will be closed throughout construction.

In March, all vehicle traffic will shift to the west side of Woodbine Avenue as crews work to widen the bridge's east abutment. The eastern sidewalk will be closed and a temporary pedestrian walkway will be installed.

Metrolinx expects work on the bridge's east side to be completed in July, at which point crews will begin to widen the west abutment. Traffic will then shift to the east side of Woodbine Avenue and a temporary pedestrian walkway will be installed.

Throughout the first stage of construction, work will occur between 7 am and 7 pm from Monday to Friday. During construction on the east and west abutments, crews will also work overnight from 7 pm to 7 am from Sunday to Thursday.

Drivers, pedestrians, and cyclists alike are encouraged to consider alternative routes and account for extra travel time while construction is underway.
