The plaza is a great street park located under the SkyTrain between Main and Stadium station. It includes stairs, banks, rails and boxes. The overpass above provide shade and cover from rain but also less-than-clean air.
In 2005 the city of Vancouver offered local street skaters this great spot under the SkyTrain and overpass as an alternative to skating downtown. Everything is laid out as you would expect in a proper street plaza and of course everything is grind-able. The overpass and SkyTrain track offer some protection against both the sun and the rain and the place is lit all night long.
