Unfortunately, in typical backward BC style, the bridge project was cancelled. An 8 lane tunnel option without any provision for a train isn't expected to open until 2030.
The Oak_Street_Bridge could have been modified to be 4 lanes northbound, if a new bridge west of it was built to handle 4 lanes from Granville Street going into Richmond.
BC has never been able to thwart the scale of infrastructure in Alberta and Washington State, let alone Ontario and Quebec. So those places and many more, are always to build on a larger scale than what is allowed in backward BC.
Most of Oak Street & Granville Street are 6 lanes wide. That's 12 lanes that never has to become a freeway, just a more efficient traffic corridor.
The 8 lane Granville_Street_Bridge could have been modified to handle 4 northbound lanes from Oak and 4 southbound lanes to Granville Street. Then like what several other cities do, is build more parallel bike bridges so that lanes don't have to be removed from the Granville_Street_Bridge & others.
That's what happened to the former 6 lane Burrard_Bridge. Now the Burrard_Bridge is a classic 4 lane funnel because the city was too cheap to build a parallel bike bridge.
The Ironworkers_Memorial_Second_Narrows_Crossing should have been designed to have 4 lanes each way plus 2 full width emergency lanes. Then by now it could have been a 10 lane bridge. A new rapid transit train & bike bridge should be built beside it.
