Toronto Green Line Underpass Solution

Toronto Green Line Underpass Solution
View of the Brown+Storey Architects' proposed Public Scaffold.

Our winning entry in the Green Line’s Underpass Redesign Competition sought to match the new social character of the anticipated park with a solution to the underpass that would activate the public realm and safely link the street, bridge and gardens.

To bring a continuous cycling and pedestrian pathway across the underpasses that dominate the Green Line, we proposed cantilevered pedestrian bridging alongside the railway bridge structures. Over the new bridge, an ephemeral scaffold is constructed with a glass framework, built high enough to form both a generous sheltered route and a look-out. The scaffold construction provides a kiosk and storage space for bikes. Its glass skin becomes a solar collector and lamp on the south side, and a surface for art, community notices, dialogues and paid messaging on the north side.

In addition to the ramps from the Green Line, wide, safe public stairs connect the street to the scaffold passage. The importance of these stairs is underlined by proximity to new ‘Exchange Plazas’ at street level on each side of the bridge. These hard surface plazas are raised plinths that punctuate the street and multi-use path. These plazas, together with the scaffolding, create new landmarks in the city – new public spaces, cycling and skateboard friendly, linked directly to the Green Line with constructed hedges, light, space, resting places, and a variety of amenities. The new Dovercourt Exchange becomes a pluralistic landmark for passage east and west, north and south, up and down and across.
