Furthermore, the pathetic single 'left turn lane' to access Northbound Alex Fraser Bridge from the 91 Connector needs to be improved.
Of course, in the interest of ensuring the tolled option is the preferred option, I can see the Province purposely keeping these key congestion points in place along the Hwy 17 / 91 corridors. I hope I'm wrong. I know there is funding in place for a 91 / 72nd Interchange, but it seems to be dead in the water (see my other thread about that).
I guess we can wait for the preliminary designs to come out -- I'm really curious to see how 10 lanes are tied into a corridor that really can only support 6 along the entire route.

There is not much you can do about the single left turn lane onto the AFB. I guess you've never driven down Nordel during rush hour? It can often back up to Scott Road. Most of the traffic making that turn is traffic skipping tolls at the PMB (and one day skipping tolls on the PB and GMT-B), they deserve to play second fiddle to local residents using their local bridge. The staggered nature of the left turn there also help the bus queue jumper.
They do need to widen the overpass over the 91 so that traffic NOT making the left turn can get past the queue and make it up Nordel without having to wait half an hour.
And they need to add the interchange so that through traffic on the SFPR can make it through there easier.

Showing those designs of the Steveston/99 interchange I don't see how they can possibly do it.
Also...............why stop the HOV lanes at HWY#91 ? HWY#99 is busier between 91 and KG than between #91 and Ladner Trunk. Very odd and I hope WR and Surrey put pressure to get it all the way to at least KG.

The HOV plans stops at the 91 because there are already HOV lanes between the 91 and King George on the inbound side. They just need to repaint the lines so the HOV lane is on the inside. But yeah, they should also add an outbound HOV lane and replace the King George interchange while they are at it (the overpass is pretty old) with HOV lanes to the park and ride (so the buses don't need to change lanes). But as far as things go, that stretch outbound is usually one of the better moving parts of the 99.
I bet it will be an integrated bus platform in a second HOV lane, with an island platform between the lanes and stairs up to bus stops on the overpass (similar to some of the ones on the I-5). That way you can make a simple cross platform transfer from the 351 (from South Surrey) to the 420 (to the ferries). Unless you also build a fancy exchange at the 17A; but it might be nicer to let buses fly through one end and only stop at the other. But I think they will add dedicated bus exits at 17A.

There are roundabouts like that at the hwy 99 8th ave interchange. And they are not so bad, even when it gets pretty busy. I feel it is faster than if they had a light or 2.
With dedicated ramps from the 17A to 99 taking most of the traffic at that interchange, the traffic using the roundabouts would be pretty low.

Would this imply they are going to add a proper shoulder, or add/drop lane, or both?

I actually think they have that backwards. That overpass is wide enough for the lanes they propose.
But under the Cambie overpass is NOT wide enough. There is only room for 2 lanes under each truss. There is no way to have 3 lanes together (center HOV lane and 2 GT lanes). That overpass (technically 2 overpasses put together) needs to be replaced.

Due to the HOV/bus lanes being in the far left lanes as opposed to the far right like they are now, it's going to be quite difficult and very expensive.

We did get quite a bit of that though. The stuff that is missing doesn't really mater because of the tunnel bottleneck. The HOV lanes are in place on the North side, and on the South side, only a small stretch is missing. And those additions required a lot of work. At least 6 interchanges were significantly altered to accommodate them.
And what's going to be expensive? For the most part, the lines just need to be repainted. Move the diamonds to the left lanes.
