Toronto’s Underpass Park shows how land beneath major roads can become usable public space without removing the infrastructure above it. In the West Don Lands, the 1.05-hectare (2.5-acre) park combines a playground, basketball half-courts, skateboarding facilities and flexible event space beneath and around the Eastern Avenue, Richmond and Adelaide overpasses. It opened in phases in 2012 and 2015.
Where Underpass Park is—and what it changed
Underpass Park sits in Toronto’s West Don Lands, beneath and around three overpasses: Eastern Avenue, Richmond and Adelaide. Rather than treating the shaded, column-filled footprint as unusable leftover land, the project made it part of the neighborhood’s public realm. Waterfront Toronto describes the park as helping connect the community on either side of the infrastructure and nearby parks.
The overpasses remain in place. Their columns, beams, shade and segmented spaces became conditions the design had to work with, not obstacles to erase. The resulting park covers 1.05 hectares (2.5 acres), according to Waterfront Toronto’s project page.
What people can do there
The site brings several kinds of activity together, so it can serve everyday recreation as well as gatherings and programmed events.

- Play: A playground includes swings, climbing structures, a teeter-totter, hopscotch and four-square.
- Basketball: Two half-courts provide space for informal play.
- Skateboarding: A skatepark includes obstacles, rails and ledges.
- Gathering and events: Flexible community space can host markets, festivals and seasonal events.
The mix is central to the project’s approach: the underpass is not simply decorated, but organized for different uses across a public space.
How the design responds to an underpass
Shelter, light and visibility
The bridges provide weather protection, making the area usable in conditions when an exposed space might be less comfortable. Lighting is also built into the design: documented elements include LED fixtures on columns and in-ground or in-wall lights. These are design features intended to make the spaces usable and welcoming; the project accounts do not establish measured safety outcomes.

Planting and durable materials
Waterfront Toronto reports 54 trees, including Kentucky coffee and black locust trees. Planting choices include drought-, salt- and shade-tolerant species intended to reduce maintenance and irrigation demands in a challenging urban setting. Materials include recycled content on play surfaces and reclaimed granite cobblestone.
The landscape design team was PFS Studio with The Planning Partnership. The American Society of Landscape Architects describes the project as reconnecting neighborhoods and nearby parks through an active public realm: ASLA’s Underpass Park project account.
Phased delivery and project cost
The park was delivered in stages. Waterfront Toronto records the first phase’s official opening as August 2, 2012, and says the western phase opened in 2015. The Urban Land Institute’s 2020 case study also identifies 2012 and 2015 as the opening years for the two phases.
That ULI case study reports a project cost of C$9.5 million. This is a historical figure reported in its 2020 publication, not a current construction estimate or a cost basis that can be transferred to another site. The report is available as Pavement to Parks: Transforming Spaces for Cars into Places for People.

What the project demonstrates—and what it does not prove
Underpass Park offers a concrete construction and public-realm lesson: transportation infrastructure can remain in service while the space around and beneath it is designed for recreation, gathering and neighborhood connections. The project’s documented strategy combines several uses, lighting, shelter, robust materials and planting selected for site conditions.
The available project and professional accounts describe design intent and facilities, but do not provide measured attendance, user-satisfaction results, crime statistics or evidence of a safety improvement. Those effects should not be claimed as established outcomes on the strength of the project descriptions alone.

Certification context
Waterfront Toronto says the project formed part of the West Don Lands’ Stage 1 Gold certification under the LEED for Neighbourhood Development pilot program. That is the certification context given for the broader development stage; it should not be read as a standalone LEED certification awarded solely to Underpass Park.
