Just got back from a weekend trip to Ottawa. (Freddy to Ottawa Friday, Ottawa to Freddy on Sunday).
There's a 40km stretch between Riviere de Loup and St Louis de Ha-ha that still needs to be done, otherwise it's fantastic four lane highway all the way through.
Quebec did 'cheap' out by just expanding the highway to 4-5 lanes through some of the towns instead of having 2 separated highways; but for the most part, it was a good sweet ride through. The old Irving Truckstop right at the Quebec border's days will be numbered; it isn't too far off the highway, but it's not obvious how to get to it if you didn't know it was there.
The A30 around Montreal is a fantastic bypass. There's a slight clog due to construction where the TCH and A30 meet, and the exit to the Island also backs up bad as well (at least when we went through) but otherwise it was smooth as silk.
Only issues with it:
* Notification that it has a Toll caught us by surprise. Furthermore there was no pricing signs until you actually GET to the Toll station; hard to prepare your money ahead of time.
* The west end connection to the A10 and A20 could use some ironing out. They were fine enough, but seemed a bit too turny for a modern highway basically.
* Google Map's was still trying to keep us on the TCH and across the island even with A30 available.
As for Ottawa itself, it's the first time I've been up there in 10 years, and I was blown away by how much its changed. One of the biggest things I took from it though (since we were staying in the West end) is that the city needs a new East-West Controlled access artery. The Queensway is too deep in the city and has way too mcuh traffic (especially with construction going on).
We crossed back West to East south through Barhaven and that's just packed full of places now. Maybe the province should start planning a new highway now, getting land now and controlling access; maybe around Route-8 around Manotik feels about right (from my extremely limited experience); just to link 417 and 416 basically.
Anyways, just some observations from my trip.

Hopefully it won't be another 10 years before I head westward by road.
