M1:Does M1 extend from "SeeRamAir" back to "ToAir" as OSM suggests? Check
Official data. The "Road Map" has no date and seems to be outdated but the "List of Classified Roads" is from Jan 2021 (both were likely uploaded in March 2022). The list only indicates "Plaine Magnien Roundabout to entrance of Sir Seewoosagur International Airport, including all adjoining lanes for access and exit." which is the diverting junction and "all" lanes to the airport. I think we should extend the route!
You might add a rda.govmu.org link to credits.php
A10_PMN is A12!
Add wp for GSJ between ToAir and B79
Add wp for GSJ between B81 and A10_S
CorRd -> B86 (see subsequently for existing B86)
GenCaenSt -> B63
Add wp for GSJ between B6 and B71
B86 -> B68 but routes don't intersect
ToM3 -> M3_??? see
List of Classified Roads and subsequently
Add wps for two GSJs between A1/A8 and A10_N
Add wp for GSJ between M3 and A7
MtOryRd -> B46
Add (shaping) point for GSJ u/c between MtOryRd and NewRdSor (construction looks quite advanced)
GreLn -> B77
Remove A1 wp because routes don't intersect.
However, there are two ramps (not full i/c) south of the bridge which need a wp. I'd but it between the two ramps
