Adams Outdoor Advertising took home the Best Billboard Campaign award for its "Big Slushes" ads for Sonic Drive-In at the Outdoor Advertising Association of America's Obie Awards on Tuesday night. The campaign turned billboards in the Charleston, S.C., area into giant slushes complete with 3-D straws.

Kenneth Cole Productions and the Seattle Aquarium won the other two major awards.

Cole won the 2015 Best Street Furniture/Transit/Alternative Campaign award for its "Be the Evolution" campaign in the New York subway, which urged men to perform good deeds throughout the day, like giving up a seat on the train or taking a photo for a tourist. The ads promoted Cole's Mankind Fragrance.

Seattle agency Copacino+Fujikado was presented with the 2015 Best Multi-Format Campaign award for the Seattle Aquarium's "Amazing Facts" campaign.
