I came back to visit family and was happy to see the 104 twinning to Antigonish is complete, although I was driving back at 1am so everything was pitch black. I had also just came back from a trip to the Sydney area on Sunday - took the St. Peter's route up there and the Eskasoni-Iona-Queensville stretch on the way back.
The Port Hawkesbury-St. Peter's stretch appears to be easily twinnable but the route up through Ben Eion / East Bay seems like it would be difficult to twin due to the topography and amount of houses & cottages along the route.
As for the South Shore route discussion from a few pages back, I think it's important to plan these sections ahead of time even if the ADT currently isn't perfectly in line with warranting expansion
today. That whole route from Hammonds Plains to Bridgewater is and will be the biggest growth sector in the province going forward; if you want growth you have to plan right now for the capacity upgrades. Our problem here is we only wait until everything is FUBAR before we even go to the planning and design phase while everything is stuck in gridlock and people are dying from preventable accidents in the short-medium term.
I can't believe I'll say this, but look at New Brunswick (
) for better highway planning and upgrades. Credit where it's due.
