A-50 was intended to serve as a link from Ottawa to Mirabel International Airport. This unfinished autoroute contains numerous at-grades, including five cross-streets (no traffic lights) and two railroad crossings. These at-grades are the main problem on A-50, apart not being completed!
This road is unsafe because to link both sections, motorists have to use QC 148, an unsafe road which traverses a number of small towns and has considerable truck traffic, for a significant distance. In the Hull-Gatineau-Ottawa area, the traffic is heavier. The interchange between A-50 and A-5, a double-semi-directionnal-T(which tells you a lot by its name) do not help congestion.
The pavement on the eastern section of A-50 from A-15 to the Mirabel Airport terminal is hideous, but the super-2 one is better. As for the western section of A-50, it is a typical autoroute pavement full of cracks and potholes.
The MTQ does a fair job of signing A-50, though it could include trailblazers along QC 148 between the two isolated sections. In downtown Hull, there are some main streets that are not indicated because their access is made via A-5.
As for aesthetics, I have nothing to say. A-50 remains an autoroute. There are no great panorama views or scenic things except the Ottawa skyline when crossing the Gatineau curve.
