Great post and very true that Vancouver is fortunate not to have a monstrosity highway in such a prime location. The same type of elevated highway was constructed in San Francisco in the 1950s as the Embarcadero Freeway and the only thing that saved the waterfront was an earthquake that brought portions of the elevated down. The rest of the elevated highway was torn down after much debate following the earthquake. Now, the SF waterfront area is once again accessible to the rest of the downtown areas. It is SO MUCH NICER than it was before.
