Man. Ya gotta be kidding me. 3 GP lanes are already extant in morning/afternoon rush hour in each GMT direction with counter-flow. Sometimes afternoon SB traffic can be backed up to the Oak St. Bridge - with 3 GP lanes. Just add another HOV lane? For what? Current HOV lane is rarely utilized except for buses.
And major commercial rigs will have to enter from Steveston interchange SB, for example, at ~50 km/hr climbing uphill on a new bridge, further slowing down traffic. Alex Fraser Bridge realizes major slow-downs/congestion with major commercial rigs climbing uphill NB from Nordel Way on-ramp - with emergency flashers on. Completely slows down/snarls traffic.
And the Alex Fraser Bridge/Hwy 91 combo witnesses major congestion and diverted GMT traffic already.
You always say "compromise on 8-lanes". Compromise with who? NDP/Greens are against new GMB. Why bother to replace it then? Just not worth it.
Any traffic engineer worth his grain of salt will always advise to have a higher number of lanes on a bridge crossing than the through lanes attaching to same. Why? Because at every bridgehead, major arteries also dump traffic onto the bridge-deck aside from through traffic.
Every Metro Vancouver regional bridge structure has witnessed same to date. Congestion central.
