Roads Fantasy Thread

[Mininari]

We all keep speaking of this purported future H-99 project. It is understandable that no thread exists for a project that is but a thought, but since a major rebuild of Highway 99, the Oak Street Bridge, and the George Massey Tunnel is likely, I thought a thread was warranted.

So, lets put speculative ideas together and design this massive 'gateway-esque' project!
Would you add a C/D system?
Which interchanges should be completely reconfigured, added (or removed?) Would you advocate linking H-99 to Boundary Road instead of Oak Street?
How will the George Massey Crossing expanded? (laning?)
Would you have truck lanes?
Would you factor in space to extend the Canada Line?
Or go with Rapid Bus?
When would this start / finish construction, and finally...
who pays for it? (tolls!)

Its all speculative of course, but theres enough talk about H-99 to start putting it all together.
