Drove Highway 16 from Edmonton --> Prince George again recently (do this many times a summer).
Lots of work has gone on in the last few years. Obviously twinned from Edmonton to Hinton, after which it's standard 2-lane highway.
They've added a
lot of passing lanes, and have re-done large parts of the highway between the Tete-Jaune junction and Prince George. Never stressful driving there.
Wish they could do more about the sections from Hinton to to the junction though. You barely see a passing lane (due to geography mostly), which leads to some pretty unsafe passing practices by a lot of people who need to get somewhere 5 minutes quicker. Found myself stuck in a line of about 9 big-rigs who can't do much more than 70 through a lot of that. Patience is key.
Beautiful drive though.
