The Setup Network Lines/Rout List window shows all of the routes (current and former) in your linear network along with the minimum and maximum mile points of each. Those routes that are no longer in use will have the Is Inactive check box selected. The measurement points are editable. All other adjustments to the linear network (linear referencing system), such as add route or delete route are made by other means specific to your project's implementation, including:

• Use of the linear network supplied within the third-party GIS map that is used in the system
• Use of the GIS transactions window (if your agency does not have an interface to an external linear referencing management system)
• Use of an interface that sends LRS adjustments and then applies them to this system
