State Routes of Washington State 1:24,000 (2025), Routes in the Decreasing Direction

01/01/1996 - Marci Carte The source file was digitized from 7.5 minute USGS quadrangles using Intergraph's Microstation software. The Microstation DGN file was converted to an Arc/Info coverage with the Arc command "IGDSARC" and transformed to geographic coordinates with Arc commands "PROJECTDEFINE" and "PROJECT." Attributes were added to the linework and routes were created with the "ARCSECTION" command based on Accumulated Route Mileage. 10/01/2000 - Thomas A. Blake The route and section tables were deleted from a copy of the existing state route files. Graphic and attribute updating were done using Desktop ArcInfo 8's ArcMap with WSDOT 7.5 minute quads for reference. New routes were created using aml's in ArcInfo. This update was reflected in the 1999 LRS. 11/28/2003 - Jordyn Mitchell Existing lines from the previous LRS (Washington State Highways, 2000) were realigned to match orthoimagery. Three columns were added to the table of attributes. They are: Display, Rt_typeA, & Rt_typeB. A .dbf file containing values to be used was joined and the attribute values for the new columns were calculated. Routes were calculated while the coverage was in Washington State Plane South NAD 83 coordinate system. The coverage was then projected into Geographic NAD83. This update was reflected in the 2002 LRS. 12/01/2004 - Heather Spates Updates to the ramps and portions of the mainlines were completed in a geodatabase. Polylines were then broken out by direction and built into routes when the geodatabase was in Washington State Plane South NAD 83 coordinate system. The routes were then projected into Geographic NAD83. Frontage Roads and Local access roads were included in this edition. This update was reflected in the 2003 LRS. 01/16/2006 - Heather Spates Ferry Terminals located in the TRIPS system and selected Proposed routes( found both in TRIPS and other records) are included in this edition. Ferry terminals were located via orthophotos or the end of cartographically drawn ferry routes. Proposed route linework are compiled from paper contract sheets. A new featureclass type FTProp was made available. This update was reflected in the 2004 LRS 2/6/2006 - Heather Spates The LRS data was edited to reflect changes in the state highway system according to the 2005 Washington State Road Log. This update was reflected in the 2005 LRS. 07/24/2006 - Jordyn Mitchell Four new attributes were added with the 2006 LRSupdate (SRID, RID, RRT, RRQ). These were added to enable easier sorting and selecting of records. These were derived from the SR field. This update was reflected in the 2006 LRS. 05/21/2008 - Julie Fogde The 2007 LRS is an update of the 2006 LRS. A copy of the Lines file of the 2006 LRS was updated using the 2007 Highway Log, GPS LRS, orthophotos, highway contract plans, and WSDOT project websites. Polylines were then broken out by direction and built into routes. This update was reflected in the 2007 LRS. 06/03/2009 - Derek Drake The LRS data was edited to reflect changes in the state highway system according to the 2008 Washington State Road Log. This update was reflected in the 2008 LRS. 05/25/2010 - Thomas A. Blake The LRS data was edited to reflect changes in the state highway system according to the 2009 Washington State Road Log. A new attribute "LRS Date" was added to indicate the valid date of the measures (ARMs) used to update the data set. This update was reflected in the 2009 LRS. 03/31/2011 - Thomas A. Blake The LRS data was edited to reflect changes in the state highway system according to the 2010 Washington State Road Log. This update was reflected in the 2010 LRS. 04/15/2012 - Thomas A. Blake The LRS data was edited to reflect changes in the state highway system according to the 2011 Washington State Road Log. New attributes (RouteID, StateRouteNumber, RelRouteType and RelRouteQual) were added. They are equivalent to (SRID, RID, RRT, RRQ) repectively. This update was reflected in the 2011 LRS. 03/15/2013 - Thomas A. Blake The LRS data was edited to reflect changes in the state highway system according to the 2012 Washington State Road Log. New featureclass types "Turnbacks" and "AllPoints" were made available This update was reflected in the 2012 LRS. 04/5/2014 - Thomas A. Blake The LRS data was edited to reflect changes in the state highway system according to the 2013 Washington State Road Log. This update was reflected in the 2013 LRS. 04/1/2015 - Thomas A. Blake The LRS data was edited to reflect changes in the state highway system according to the 2014 Washington State Road Log. This update was reflected in the 2014 LRS. 3/15/2015 - Jordyn Mitchell All LRS data stored in SDE was migrated to a new server. Several attributes (SR, SRID, RRT, RRQ) were dropped, replaced, or recalculated to conform to a consistent schema. 04/1/2016 - Thomas A. Blake The LRS data was edited to reflect changes in the state highway system according to the 2015 Washington State Road Log. This update was reflected in the 2015 LRS. 03/15/2017 - Thomas A.
