</blockquote></div><br><div>Same also with A1 heading up the coast that are definitely motorway standard. The RMS has stated that these motorway sections won't take on an M designation until they are continuous between major population centres in order to avoid too much switching between A and M, so I think we are right to map these as "Motorway" in OSM - being a high standard (mostly) grade-separated road - because "on the ground" that's exactly what it is… but we have to live with their temporary "A" route designations.<div><br></div><div>With respect to route relations for the M31/A31 and M1/A1, I am guessing we will need to create a relation for the "A" section, and a separate relation for the "M" section… and then perhaps a parent to encompass the entire route.
