It's something I've been thinking about around in
http://forum.skyscraperpage.com/showthread.php?t=226949
for some time now.
The idea is that the bridge would span from the East side of Burnaby Mountain to the old Power Plant lands in Belcarra- connecting Hwy 1 to Ioco and David Avenue, and providing higher-speed access to the Tricities.
A potential extension would see it turn around to connect to North Van via Deep cove, proving highway access to the East of North Van. It would then extend to Upper Levels by skirting Seymour Provincial Park, LSCR, and connecting just east of Lynn Canyon.
Would it work?
