ah of course. Well, I did live in Latacunga about 5 years ago, and the no-HGV restriction was definitely active back then. Since then I officially have not seen with my own eyes whether the restriction has been lifted or if it is still in place. So I guess we need to send someone to have a look :)

just checked on Google maps, and the imagery still (2024) says it's no-go for hgv ✓

yeah, it's been a while though, so I don't know if the Lorry restriction still applies. But hgv=no would work instead of the previous syntax.
