2019-2021 Arkansas official highway maps (http://www.arkansashighways.com/Trans_Plan_Policy/mapping_graphics/tourist.aspx) are now available.
There initially was a glitch on-line where they showed the 2019 map, but advertised as the 2017 map, but that seems to have been fixed. At a glance, the map looks too busy with every little historic site labelled.
