This feature class was derived from postmiles validated in the Caltrans Postmile Toolbar version 1.4.04 from a spreadsheet obtained from the Caltrans HQ Structure Maintenance & Investigations (SMI) which was derived from the Structures Maintenance Database. The postmiles used the Linear Reference System from the Teleatlas road data as the base reference layer.The purpose of the ST_BR feature class is to represent bridges in California that are located on the California State Highway System.Caltrans HQ Structure Maintenance & Investigations (SMI)20060627st_brvector digital datahttp://www.dot.ca.gov/hq/tsip/TSIPGSC/library/libdatalist.htmpublication date20060627-124.250609-114.30034642.00218332.542160-124.250609-114.30034632.54216042.002183Shapefile Caltrans TSI/GIS Data Branch Metadata Coordinator mailing and physical address Sacramento CA 95814

The majority of the bridge locations were generated this way. There was 53 bridges that the postmiler did not validate and so this list was generated using the Latitude and Longitude of the bridges as an XY event layer, and then remerged with the validated bridges. The postmiles used the Linear Reference System (LRS) from the Teleatlas road data as the base road reference.Caltrans Postmiler Version 1.4.04, ArcGIS 9.1SMI200606The Structures Maintenance database has undergone modifications in 1997, including the conversion of data to the metric numeric system (with exception of postmiles) and the removal of data attribute redundancy. The location of the bridges in this feature class are based on postmiles from the Caltrans HQ Structures Maintenance database. All data in this feature class was imported from the Structures Maintenance database. The items in the Point Attribute Table (PAT) are a partial list of the items in the Structures Maintenance database. For more information about this database, contact the Caltrans Office of GIS. The bridges in this feature class were placed with dynamic segmentation and are based on the postmiles in the Caltrans HQ Structures Maintenance database. The postmiles used the Linear Reference System from the Teleatlas road data as the base road reference. Bridges with inaccurate postmile information were located using latitude and longitude. This is represented in the data table under the PMSTATUS.This feature class is updated annually. The Structures Maintenance database is continually updated. Users of this feature class should take note that state highway bridges entered into the Structures Maintenance database after the latest feature class update will not be represented in the feature class.
