4 lane new bridge old bridge retained for pedestrians
Make the new bridge (Mandurah Rd) four lanes to stop the congestion there at 8am EVERY SINGLE WEEKDAY.
Image isn't the old bridge that you are voting on. Not sure where you think the new bridge would go along side. Should we sacrifice the old Tuckeys building or Dalrymple school house aka the museum.

New one needs to be more than 2 lanes, but would love to keep the old one.
