Looks like the road has been removed in favour of a central courtyard. From the webpage:
"The plan proposes a 204 suite 19-storey market rental apartment building and a 10-storey office building, both fronting on King George Boulevard, a 42-storey condominium apartment building in the site’s southwest corner and a 36-storey condominium apartment building in the site’s northwest corner.
Along King George Boulevard will be an active retail/commercial frontage directly across the street from the SkyTrain Station, creating a mixed-use podium on top of which will be an
expansive courtyard between the four towers, providing richly landscaped and programmed public and semi-private spaces, activated around the theme of food and urban and agriculture. This courtyard space will create a sense of community among on-site residents, office workers and visitors, allowing them to flow across a new parkside street and enjoy the open space of Holland Park."
