GA by number is a contest for WikiProject Highways destined to increase the number of road Good articles throughout Wikipedia. The goal of the contest is to get a GA for every number from 1 to 99. It is strongly encouraged for editors to pick stub-class articles to expand to GA in order to reduce the stub count. There is no time limit to this contest, so take your time to make sure the articles are decent.
