A gantry is a large framework that holds signs, traffic signals, cameras, or other equipment above the road. It is usually made of metal and is built to stand strong and support the weight of the items it holds. Gantries are commonly found on highways or busy roads where they are used to display road signs, monitor traffic, or collect tolls. These structures help ensure that important information is clearly visible to drivers while keeping equipment safely above the road.
