1. Decreases the limit at intersections;
2. Increases the limit within an urban district, but not to more than 55 mph; or
3. Decreases the limit outside an urban district, but not to less than 25 mph.
b. Any alteration of maximum limits on state highways or extensions thereof in the town, under the provisions of this article, shall not be effective until such alteration has been approved by SCDOT.
