With most of the regional bridges being too narrow, there isn't enough space for proper express bus+lanes or BRT lanes. Plus, the first 2 Skytrain lines only have the potential to accommodate 5 car trains. The Canada (Embarrassment) Line wasn't designed to eventually have 5 car trains, only 2.5 car trains. Narrow bridges and short trains are all part of the symbolic reluctance towards having proper big city size infrastructure.
