Thieving Bastard's CK2-AGOT Trade submod (AGOT v1.9.1+)

Sure!


Essosi Trade Routes

Northern sea route starts in Nefer, goes trough all northern islands, Essos rivers, bays and ends in Pentos.
Southern sea route starts in Ulos/Asshai, goes trough southern islands, bays, Rohyne River and most important ports and end in Myr.
Land routes in far east start in Trader Town and in Yin and go trough the Steel Road, Stone Road, Sand Road and Jade Road, ending in Meereen and Essaria.
Land routes in near east start in Morosh/Saath and Astapor and go trough Essaria in Slave Road, Demon Road (south) and Spice Road (north) and end in Pentos (north) and Volantis (south).




Westerosi Trade Routes

The more fishy routes squirming around major rivers, bays and fjords are sea route continuations and the land based ones are the standard Kingsroad, Roseroad, Oceanroad, Riverroad, Highroad, Stormroad, Boneway, Bloodpath.




The routes try their best to follow the following "official" map about major land routes and sea ports, but due to differences in the game map and official, I just couldn't get Boneway to cross Summerhall so that it would look sensible, as then a trade route that is supposed to be easy to travel would cross impassable mountains that armies can't cross. Sorry ghosts of Summerhall, you must find some other targets to spook than traders.

Also due to the older engine limitations of CK2 compared to EU4, I don't seem to be able to nudge the routes to look better. Actually the nudge tool of CK2 doesn't have anything related to trade in the first place and even the functions it does have doesn't seem to be saveable in the mod map of AGOT for some reason, so needed to settle for using the built-in movement paths of the counties and thus the routes look as they do.
