This feature class is a combination of structures which are an extract of FDOT Bridge Inventory. It is maintained in a restricted database called the Bridge Management System (BMS), formerly PONTIS. Monthly the GIS unit extracts/updates this feature class via script for the visualization of bridge structures in GIS. Bridges (which includes mast arms, high mast light poles, and large sign structures are represented as points at the start of the structure in the direction of travel of the roadway. A structure number is inset at the begin point of the structure in the direction of travel. Some Bridge numbers represent both directions of a two structure bridge. In other cases a second number is given to the separate structure for the opposite direction of travel of the roadway. Included also are Pedestrian Crossing Bridge Structures, High Mast Light Poles, Mast Arm and Sign Structures. Mast Arms represent an intersection where one of more mast arm structures support traffic signal equipment.
