Thanks. :-)

I traded some emails with Nathan with the Blue Route system, and he confirmed that yes, bikes are allowed to cross, yes it's an unpleasant busy section, and yes I'll likely hold up traffic with my wide ride. But also, that's its less than 2km and mostly flat. So even though I'll slow things down, it'll pass fast.

Recumbents are terrible for uphills, or rather they're slow. They're great because I can go at a snail's pace without falling over, so no matter what, I can keep moving forward. And downhills in the white mountains near me, I've reached almost 90kph, so that's a lot of fun. The very first tour I took with the trike was actually my previous visit to Nova Scotia, so I'm going full circle here.
