Geometry and Attribution: The dynamically generated points contained within this feature class portray the beginning of structures represented on the master route in the prime and the end of structures in the non-prime directions of travel. All point locations are positioned on Linear Referencing System geometry based on latitudinal and longitudinal coordinates initially obtained from heads-up digitizing in the Geographic Information System. Structure coordinates are currently maintained in the Roadway Network System by the Structures and Bridge Division. Features on or along the road (culverts, bridges, tunnels, parallel footbridges, etc…) and also features crossing the road (overpasses, culverts, perpendicular foot bridges, etc.) are depicted in this data. Business attributes for all features are derived from Pontis (Bridge Management System), the structure source system of record.

Purpose: This feature class serves as the Structure and Bridge Division's spatial reference allowing BrM (Bridge Management System) data to be viewed, analyzed and mapped within Geographic Information System applications.
