I think six lanes from the new Brooksbank interchange would be fine and much more politically possible.
I agree with this. I don't think that an additional lane south/eastbound down the cut is required. All that would do is get traffic to the bottleneck faster, it wouldn't reduce it. It may
benefit the 1-in-20 cars that gets off at the new Brooksbank interchange, but that's not a priority.
A 6 lane bridge over Lynn Creek will be required though at some point. It will greatly help the merge from Mt. Seymour Pkwy -> Hwy 1 Westbound. I still think until there is a 4th lane of traffic southbound over the Ironworkers there will continue to be a bottleneck at the bottom of the hill though. There are 5 lanes of traffic (Mt. Seymour Pkwy/Fern Street, Dollarton west/southbound, and Main Street east/soundbound, plus the 2 Hwy 1 lanes) fighting for space in 3 traffic lanes over the bridge. It will never be perfect in rush hour. Getting the traffic moving east/west over the highway at Mountain Hwy/Fern St and Main Street/Dollarton is the biggest priority to reducing congestion on either side, as realistically a new bridge over the 2nd narrows isn't happening any time soon.
I'd also like to see some improvements from cyclists over the highway. Fern Street isn't so bad, but the Main Street/Dollarton transition is probably the worst/most dangerous section for bikes on all of the north shore (especially eastbound).
