What does ACHT mean in Advisory?

Acht

This is a List of Ontario Tourist Routes throughout the province, which are designated to highlight places of cultural, environmental, or social importance. It is currently unknown if the majority of these trails are still listed since many of the provincial highways of Ontario were decommissioned in 1997 and 1998, as the Tourist Trails followed the provincial highways for the majority of their length, although many sections travel along county roads and municipal/local streets as well. Although many municipalities, cities, and counties still sign these tourist routes, others may have chosen to discontinue them with the highways they followed, rendering them as historical footnotes.
