Indeed, why build a bridge with 2 bus lanes & 2 HOV lanes & even 2 emergency lanes? Just cram everything into only 2 lanes each way. This is the epitome of BC bottleneck planning. It's also another symbolic example to water down the scale of the infrastructure. Building big & wide is indicative of planning for growth, but BC has been under a multigenerational slow growth agenda.
Bus & HOV lanes should be standard on any new bridge in Greater Vancouver. A 4 lane bridge is just another sad BC joke. Make sure that the bridge isn't designed to accommodate a future deck for LRT, because Surrey & NW won't ever need another rapid transit crossing. Properly planning for growth means thinking big, but this is small minded backwater BC.
