As I already mentioned in the Telegram I found 10 new hidden roads in Missouri – 3 in Rolla, 1 in Jefferson City (in the video below), 2 in Joplin (one is update for road in Pittsburg, Kansas), 1 in Maryville and Kirksville and 2 in Poplar Bluff. Searching in progress. So probably soon will be update for 203 roads guide (which is obviously will be bigger) and you can follow the progress on the list of secret roads https://trucksim.top/y9t6
On the below video I found another gorgeous hidden road in the Ozark area #CruisingMissouri. It is not Road trip mode yet, just mod car 2021 Dodge Charger SRT Hellcat. Hope one day to reproduce it with vanilla car in game.
