Decorative Yield Signs. The front is a normal yield sign, but in Donnelly they have done something different, by decorating the back of all yield and stop signs with a colorful image of the community. The normal sign posts have been also replaced with something more decorative. One of the Avenues is called "Gravel Avenue" which runs from the Sportex east across the village. It is named after Marie-Anne Leblanc Gravel, one of the first homesteaders of the area. Donnelly, Alberta.
