Gantries in the context of outdoor hoardings or billboards refer to large overhead structures that span across roads or highways. These structures are designed to support and display advertising panels or billboards in a prominent and highly visible position. Gantries are strategically positioned at key traffic junctions, toll plazas, or other high-traffic areas to capture the attention of passing vehicles and pedestrians. Gantries offer advertisers a prime location to capture the attention of a diverse audience and are a key element of out-of-home advertising strategies, particularly on highways and major roadways.
