Bridges can be added to component roads. Use in-canvas sliders to specify the start and end station locations of a bridge within a component road and thus determine its length. Select a bridge and press the delete key to remove it from a model or proposal.
Note: You can [convert a planning road to a component road](https://help.autodesk.com/view/INFMDR/ENU/?contextId=InfraWorks_convert_plan_road).
InfraWorks supports precast Concrete Girder, Steel Girder, or generic bridge styles.
Single-click to place the start station.
