However, there is one major caveat with the plan. For the shutdown to occur, the agreement stipulates that a new replacement crossing across Burrard Inlet from Vancouver to the North Shore would have to be constructed.

Any crossing replacement or expansion option would have to consider the reality that downtown Vancouver’s street grid does not possess the capacity to handle a significant increase in vehicle traffic volume. This could be further exacerbated by the City’s plan to demolish the Georgia and Dunsmuir viaducts, which will redirect traffic to other adjacent arterial streets.
