Hubby and I did it in 2013...ferry from Newfoundland to Lab City and down to Quebec and home to NY.
More was paved than I could find online before we went...THAT was a nice surprise.
Read my
blog post about the trip to see if it is for you.
In a nutshell the part in Labrador was "okay" and probably what we expected as far as road was concerned....meaning the unpaved parts...and since it was gravel we didn't expect a lot. We really didn't expect it to be washboard and mostly it really was not. The paved parts were a FINE gift. It took some experimentation to figure out how to "drive" on the gravel. It was NOISY (all hell broke loose in the back of our class c) and I had to run around back there and quiet things down as much as possible.
The Quebec part...suffice it to say (more details in blog) that had we started in the Quebec province part, we both would have turned around. YET, we did see two rv's (coming at us from that direction before we hit Lab City....and only two!) We assumed they had come up the Quebec route 138. Quebec portion was pretty hilly, ziggy zaggy, weavy winding...and my husband really wanted to have someone show the grader how to do the job. It is a transport route basically from south to the mines/dam....with trucks and some big ones trying to do their jobs. They are not driving 45 miles per hour but hauling it.
Labrador was drop dead georgous and I would do it again...when the road is paved all the way to Lab City. Not sure what I would do with the Quebeck portion...most likely plan my travel carefully to not have big trucks barreling down behind us. (We were fortunate and did not but I could see it could be a big problem with little places to pull over and they are in a hurry and experienced in driving this road).
We drove at around 45 miles per hour...which seemed to be the sweet spot if that particular portion of the road was not washboard. Mostly it was not washboard. Slower and it was noisier and faster...pretty much ditto. Road graders are there and working on it all the time. They are actively paving or prepping for paving.
Bring lots of food. We didn't do the satellite phone but luckily had no problems. You WILL NOT see many cars or trucks before you hit Churchill.
