The Expo deck outside of Science World

New Expo Deck path to open late May

April 11 2025 –

Vancouver Seawall and Seaside Greenway path users will soon be closer to the water when walking or cycling by Science World. Construction on a new compacted gravel path between Creekside Community Centre and Science World is now underway. The new wider, separated path is anticipated to open in late May, improving access around False Creek this summer. 

While the new gravel path is constructed, Seawall and Seaside Greenway path users will continue using the temporary detour routes along Ontario, Switchmen and Quebec streets. 

Expo Deck closure 

In February, out of an abundance of caution, the City closed the Expo Deck south of Science World, including the nearby Seawall path. Recent findings from regular ongoing inspections of the aging deck confirmed that portions of the structure are reaching end of life and may no longer be safe for public access.  

Since the closure, a temporary detour has been in place while the City and consultants further assessed the condition of the structure and identified an improved path to reconnect pedestrians and cyclists to the Seaside Greenway.  

Once constructed, the new path will remain in place while the City continues long-term planning for the future of the Expo Deck. A section of the south deck is expected to remain closed to the public indefinitely.   

New gravel path 

A compacted gravel path, similar to the Seawall path at Vanier Park, was the best choice of material to quickly and safely construct a new route around the closed section of the Expo Deck. 

Two new, wide, comfortable and separated side-by-side paths will be built for pedestrians and cyclists. The new route will seamlessly connect users from the Seawall and Seaside Greenway at Ontario St to the Seawall and Seaside Greenway paths in front of Science World. 

What to expect during construction 

The City has been working closely with structural engineers to determine a plan to safely construct a new path in the area. Pre-construction activities are currently underway. 

During construction, the grass area on the deck will be excavated and gravel will be placed and compacted to form the new path. Access to Science World remains and will be retained throughout construction.   

The City thanks the public for their ongoing patience and co-operation during the emergency closure and detour.
