Does anyone created symbols to display noise walls, doors, hydrants, turn arounds etc, or knows a source for standard symbols to create maps for interstates? Currently, we have only very simple maps for our freeways in our county, but with constructions ongoing, I would like to update our maps, but also include access restrictions, such as noise walls, doors and hydrant accesses on the maps. So, any help would be appreciated.
Thanks.
Irene
