This statewide file includes all state owned or maintained highways, spurs, connections, frontage roads, temporary traveled routes (TTR) and located lines. This data is a tool for analytical dynamic segmentation of all state owned or maintained highways for placement of features along the linear network in ArcGIS. This data provides a detailed view of the state highway system based on the Linear Referencing System (LRS) used by Oregon Department of Transportation. This data is intended for use at scales of 1:24,000 or smaller. 2011 Unknown publication date Complete Annually -124.500260 -116.774660 46.224070 41.918220 State Highways 2011 highway linear reference system LRS roads highways road 1:24 000 measured shapefile transportation hwynet hwynet_2011 State_Highways State Highways State Highways State Highways 2011 Oregon United States US USA Pacific Northwest Oregon OR 2011 2011 None None Geographic Information Services (GIS) Unit, Oregon Department of Transportation (ODOT). mailing and physical address

SHAPE was generated from ArcGIS software. RDWY_TYP, EFFECTV_DT, GIS_PRC_DT and SEG_EFF_DT were determined by the Geographic Information Services Unit. This file is complete at the time of posting and is dependent upon receipt of completed contract/construction information at the time of posting. Horizontal positional accuracy has been determined to meet or exceed NSDI map accuracy standards for 1:24,000 scale maps. Accuracy was determined by the combined use of USGS digital ortho photo quads and the NGS benchmarks to apply an accuracy statement to the highway linework via verification of known and visible NGS benchmarks on the orthoquads. 3.677724 See the highway accuracy worksheet for 1:24k highway baselayer on \\sn-salemmill-1\GIS\DATA\shp\docs\highway_accuracy_worksheet.xls No vertical positional accuracy has been determined United States Geologic Survey Denver, Colorado 80225 or Reston, Virginia 22092 1995 map USGS DOQ The highway feature class was exported as a shapefile using Geomedia Pro v6.0: Warehouse > Export to > Shapefile. The file was then imported into ArcGIS where segment length was calculated and it became a measured shapefile. 2011 The shapefile was brought into ArcGIS where the attribute table structure was reviewed and where process and effective dates were added.

BEG_MP_NO The milepoint measurement of the beginning of a roadway feature which is closest to the beginning of the highway. Oregon Transportation Management System (OTMS) GIS Base Layer Development Project (GIS01) 0.020000 TransInfo (TI) measurements are based on features located to +/- 0.02 mile. EFFECTV_DT This date or time period in which the data extract is relevant or current. Geographic Information Services Unit, Oregon Department of Transportation(ODOT). END_MP_NO The milepoint measurement of the end of a roadway feature which is closest to the end of the highway Oregon Transportation Management System (OTMS) GIS Base Layer Development Project (GIS01) 0.020000 TransInfo (TI) measurements are based on features located to +/- 0.02 mile. GIS_PRC_DT The date that the data was processed. Geographic Information Services Unit, Oregon Department of Transportation(ODOT) HWY_SEG_ID A unique key field for segment identification. Geographic Information Services Unit, Oregon Department of Transportation(ODOT) HWYNAME The official state highway name. Integrated Transportation Information System (ITIS) database, Oregon Department of Transportation(ODOT) The official name of the state highway that is stored in the TransInfo (TI) database. LRS Linear Reference System highway identifier. This is a representation of elements contained in the TransInfo (TI) database used to identify a highway, spur, connection or frontage road. The first nine characters are the inventory route numbers and the last three characters are the sub-route numbers. Oregon Transportation Management System (OTMS) GIS Base Layer Development Project (GIS01) The twelve digit alphanumeric string is broken down into its components as: 1: Place holder 0 (zero) 2-4: Hwy Number 001 to 499 5-6: Hwy Suffix 00 (zero zero), AA-ZZ (alphabetic characters) 7: Roadway Identifier (1,2,5) 8: Mileage Type 0 (zero), Z (overlap) 9: Overlap Mileage Code (0-9) 10: Jurisdiction Code (S) 11-12: Two Place holders 00 (zero zero) LRM_KEY Linear Reference Method highway identifier. This is a representation of elements contained in the TransInfo (TI) database used to identify a highway, connection or frontage road. The first five characters are the inventory route numbers and the last three characters are the sub-route numbers. Oregon Transportation Management System (OTMS) GIS Base Layer Development Project (GIS01) The eight character alphanumeric string is broken down into its components as: 1-3:Hwy Number 001 to 499 4-5:Hwy Suffix 00 (zero zero) or AA-ZZ (alphabetic characters) 6:Roadway Identifier (I, D) 7:Mileage Type (Z, P) 8:Overlap Mileage Code (0-9) MLGE_TYP Identifies the type of highway mileage. Oregon Transportation Management System (OTMS) GIS Base Layer Development Project (GIS01) 0 Regular mileage. TransInfo (TI) z Overlapping Mileage: Overlapping mileage occurs when a section of highway is lengthened due to new construction. Example: A section of highway from milepoint 49.00 to milepoint 50.00 is washed out. The washed out section must be replaced, but, the old alignment cannot be used. A new alignment is built around the problem area, but the new alignment is 4.62 miles longer than the original alignment. The new distance between milepoint 49.00 and milepoint 50 is now 5.62 miles. In order to reflect the true distance along the highway without remileposting the entire road, overlapping mileage is created.
