The B.C. government intends to spend $3.1 billion rebuilding and expanding the Port Mann Bridge and connecting Highway 1 routes.

The proposed rail system would connect rapidly developing communities in the South Fraser region, and drastically reduce greenhouse gas emissions. Read more about this light rail system at The Tyee.
