Why is that stretch of road linking the airport and the A20 a motorway ? This is not a long-distance high speed highway, just a big link road between the airport and the rest of the network. I think it is the Boul Romeo Vachon formally. Could be tagged as the rest of the loop i.e. Tertiary west of the A20. The motorway_link could ne used east of the A520. 
I don; t tank the current tagging is correct. 
As a datapoint neither Google or Apple maps did this classification - they kept it a local road.  I think we need to change the OSM tagging here.
