AlignCode indicates if the postmile is on a Right alignment, Left alignment, Right Side of an independent alignment, or Left Side of an independent alignment. Where TSN considers most state highways to have just a centerline, the underlying linework that the postmiles are based upon has a line for each direction. In some cases the right and left lines are identical (where there is no median). In other cases the right and left are separated (where there is a median, or dual carriageways), but TSN treats the segment as a single centerline. In the last case...

Description: Postmiles are valid postmile points at 0.1 (1/10th) mile intervals, based on Office of GIS Linear Referencing System layer (TIGER linework). Exceptions that are included are the beginning and ends of routes (and other situations) that don't necessarily begin or end on the even 0.1 mile interval. This data is based upon the 31 December 2017 extraction from the Transportation System Network (TSN) database maintained by the California Department of Transportation (Caltrans) Traffic Accident Surveillance and Analysis System (TASAS) branch.
