I'd be iffy on Cut-and-cover on 13-17th; it's just too dense yet to start cutting up the road. Starting the cut on 17th avoids the remaining skyscrapers
You also list Broadway to Artubus as $1.8 Billion, clearly too low, even for 2010 numbers. The actual cost is increased heavily due to real estate costs- and Lonsdale is not cheap.
I'll try to reflect this with a 25% contingency cost for both yours and my lines.
Also, the number of Stations for the Lonsdale is 9, not 8. Unless it's a spur of the Millennium?
Lastly, there's no cost estimate for At-grade- BC. I'll assume $50M/km, to make the comparison more fair.
Where is the section above-grade? I want to make this as fair as possible, so I didn't touch it.
With these numbers:
With a 25% contingency for RE costs, the Lonsdale Line is $3080M, and the Purple Line is $2498M.
I doubt either would be built all at once, considering both would have comparable costs to the Broadway Extension, which is already an unprecedented amount of money on one extension.
The Purple Line is about 20% cheaper for the entire route. Is that worth bypassing Commercial St?
I'll leave that for everyone else to decide.
In conclusion: Admittedly, the Commerical-Broadway Line, though underpriced, is not as bad as I thought. Definitely some advantages, especially in a high-growth scenario where the land around current Skytrain Lines gets built up.
PS: Made a few errors, the Lonsdale line should be $3.15 Billion; see my post below for more details.
