JOIN as the name explicitly states is an investment company and they're going to want bang for their buck. Not sure how much money there is building a billion dollar bridge across Burrard Inlet, sad to say.

The article does say we could trim a little fat in the design process:

(CDPQ spokesperson Emmanuelle Rouillard-Moreau) added that CDPQ has also been able to execute REM at a relatively quick pace as they “made a point of avoiding the linear approach to planning and construction,” which is a slower process used by TransLink and the BC government.

“Operating on a single track — with Decision A followed by Decision B followed by Decision C — can be a recipe for delay and inertia. Instead, we chose to function with a design-build model. We are moving along in parallel on several fronts, which means we are allowing for progress to begin immediately on certain aspects such as planning and land acquisitions while we are ironing out design elements and compliance,” continued Rouillard-Moreau.

How much? Probably not enough to make commuter rail to Delta or Chilliwack viable.

The justification for spending money on getting rapid transit across Burrard Inlet is to avoid the need to build or replace another road bridge. Every dollar spent on rapid transit will move more people than if it was spent on a highway bridge.

And for the inevitable "what about goods transportation?" crowd, the way to solve that problem is to toll the bridges in order to shift demand and make bridge capacity available for those uses. But it's not really feasible to toll the bridges and shift demand unless you provide people with an alternative - hence: rapid transit.

Oh I super agree, but a foreign investment group doesn't really care about that.

what we should be doing is building a 3rd crossing for cars + transit, and then closing the lions gate to cars. leaving it only for emergency vehicles maybe the odd bus if it is still needed.

that would be ideal. unless we build another road crossing, the lions gate will always be needed for cars.

I agree that, in the absence of a new crossing, the Lions Gate Bridge is an essential part of the road network. However, that still leaves us with the problem of where a new crossing would be located. Anywhere other than the existing locations would require substantial road networks to handle the redirected traffic flow, which would cause significant issues with the heavily developed lands on both sides of Burrard Inlet. Unfortunately, there's only one location that allows a easy, direct highway-to-highway connection and it already has a bridge.

As expensive as it might be, we might have to consider increased use of tunnels to address long-term traffic flow. I'm probably drifting into "infrastructure fantasy" territory here, but tunnelling Highway 1 from the Kensington area to Lynn Creek would allow the IWM to be refocussed on transit and local traffic. Then, as the IWM reaches the end of its lifespan (45 years or so from now according to Bowen Ma), the replacement could be designed and built with this local/transit focus instead of having to serve two purposes.

$496/km (Broadway tunnel rate) for 9.2 km... means we'll probably have to wait a while. That could pay for the North Shore Line and a few buses.

Anyways back to the thread topic... July 29th Broadway Subway Project Twitter posted:
"#TrafficDeckCheck: At Broadway-City Hall Station, the final lane of traffic decking is nearly complete!

Crews are currently working to install girders and deck panels while traffic moves on the completed traffic deck lanes nearby."

did they do this decking for the Canada-Line? same idea, or different? i think they did, though i was younger back then and didnt pay attention to these things at the time.

I believe no except for the cross streets. Most of Cambie has the centre median and north or King Ed was one lane each way. The N/S arterials are far easier to detour from than Broadway.

Think it was totally different since most of it was cut and cover. Maybe minus some east/west road crossings there was probably nothing this extensive.

Has anyone noticed the massive temporary sewer pipe diversion pipe above ground on Cambie next to the Crossroads? It dives down under a lane and comes back up. There's a faint sewage smell when driving by.

Yeah it's insane. The smell has been bad at ground level outside the last few days. Hopefully that passes.

It won't pass unless the citizens upstream stop passing...

interesting. thanks for that. i have some memories of driving over some bridges back then. i think at city hall. thats about it though.

but boy has photo technology changed in 15yrs.

Imagine if it sprung a leak

That came to mind - but there are lots of bolts holding the joints tightly in place.

I was wondering if there was a small air leak that could be sealed.

The super hot weather isn't helping either I imagine.

Is building a 3rd crossing and turning the Lions Gate into a bridge for a North Shore skytrain something that has been considered?

Probably the last option on their list if they even considered it.

Because of the width and depth of Inner Harbour, First and Second Narrows are really the only place to put an above-grade crossing. So a 3rd crossing for vehicle traffic would likely be built alongside the Lionsgate bridge if that bridge were to be converted to transit-only.

If a 3rd crossing was built, it would probably be an above-grade transit-only crossing near IWM, or some sort of transit-only tunnel. Again, because of the depth of Inner Harbour that tunnel would either need to go close to First or Second Narrows, or be a submerged floating tunnel with all sorts of engineering and safety complications.
