It's too bad - they just had a 50th anniversary ceremony for the Trans-Canada,
http://news.gc.ca/web/article-eng.do?nid=696139 but no announcement of any Federal funding to fix it up in BC. That would have been the perfect time to announce new projects. So it's obvious we're going into the usual 5 year waiting period between batches of upgrades. And they're not done the last batch so it could be 6-7 years. (Man, I hope I'm wrong - there are still far too many dangerous areas being ignored).
Sadly, I think the announcements will be politically timed and will only occur when it makes them (prov & feds) look good when an election is coming. I think if we had elections every year we'd be done the road lol.
I recently emailed Infrastructure Canada about the schedule for twinning the highway in BC - at least in the National Parks and they told me the highway was a provincial responsibility and it was up to BC to request funding. When I pointed out that the National Parks are federal they corrected themselves. I think that speaks volumes. They're so busy waiting for provincial requests they aren't even looking at federal roads in the national parks. Hopefully complaints like mine will trigger some action.
I'm pretty sure Alberta started off the Banff upgrade plans by kicking in $50M - but perhaps I was thinking about something else. I know in Alberta they started removing the signs beside construction projects because the Feds complained. Lol, usually because it was "95% provincial, 3% local, and 2% federal" funding. So now it's often hard to tell who paid for what, but in the end it's Canadian citizens who paid 100%.
In any case, it makes no sense to upgrade the Alberta side and not the BC side - the traffic in that area between Banff & Yoho is the same at the border. Since the Feds should be focusing on federal roads they really need to have a plan for Yoho & Glacier - even if it's just a "design phase - awaiting funding" plan.
And yes, sadly it's 90 in Banff - even though it's easily the best highway in Alberta. The only justification I can see is that animals like bears can climb the fencing. But when you have such a sweet highway, and people are on 6-12 hr road trips it just doesn't make sense for people to slow down when the highway gets better. It's unsafe actually because there is such a mixture of speeds. People following the speed limit and people going 110 (including police when they aren't setting up traps right as you leave the park). Sure, the areas around the Banff townsite should likely slow to 90, but the road from Calgary to Banff is 110 - and it's not nearly as good at the 90 section within most of the park (some of the older parts are better suited to 90 - especially for all the tourist traffic in those older narrower areas - which by the way should also be upgraded)
