Invisible (in driver) 2 lane one way road used by the Yarnish L2.1 Divided highway components. The pointy end of the mesh shows the direction the road was laid down, which is the opposire of traffic flow, This was done to remind you to lay one-way highways backwards.
while this asset does not use anything by Madeline Usher other than yhe (corrupted) YARN name, she still deserves a lot of credit for all of her great work, so lets all cheer for Maddy25.
