Abstract:
This data set shows the locations of bridges maintained or owned by the Washington State Department of Transportation (WSDOT) and located on the State Route system. The bridge locations and attributes were obtained from the Transportation Data Office in an Excel Spreadsheet. Data are current as of 1/29/2004.

Bridge locations were defined in the spreadsheet based on State Route Milepost and SR/RRT/RRQ and Accumulated Route Miles (ARM) along the State Routes. These events were mapped using the WSDOT 1:24,000 Linear Reference System (LRS) and saved as a new data layer. The LRS line work was last updated on 2/23/2004, and reflects values in the published 2003 State Highway Log (2/28/2003).

Purpose: Show the location of WSDOT Bridges and to allow the user to determine the Bridge ID and Structure number. With this information the user may query the WSDOT Bridge Inventory System.
Supplemental Information:
Of the 2898 bridges, 85 were not mapped. Of these, 3 had ARM values that were not found on the route and 82 were on routes that did not exist in the LRS. The RRTs in this second group were broken down as follows.

RRT Number Not Found
CD 10
CI 13
FD 2
FI 4
HD 3
HI 2
Ramps 42
TB 5
TR 1

All bridge information is included within the bridge shapefile data table. You may use the LOC_ERROR field within the shapefile to determine if a given bridge was/was not mapped and why.

Attribute Accuracy:

Attribute Accuracy Report: Attribute data obtained from the WSDOT TRIPS database. Data current as of 1/29/2004.

Logical Consistency Report:
Data were mapped as events on the State Routes of Washington at 1:24000. The data were current as of 1/29/2004. The Highway system was last edited on 2/23/2004, and reflects values in the published 2003 State Highway Log (2/28/2003).
Positional Accuracy:

Horizontal Positional Accuracy:

Horizontal Positional Accuracy Report: The Bridge data contains State Route Milepost and ARM values good to 1/100 of a mile. As such, a bridge location may only be mapped to +/- 53 feet.

Process Step:

Process Description:
Formatted and converted the Excel Spreadsheet into four dbf files. The original data were divided into four sets based on where the items described by the data were located on the State Route System (i.e. increasing side, decreasing side, on a ramp, or on an under/overcrossing). The data was placed as events along the 24K State Route Linear Referencing System. The event shapefiles were then combined using the Geoprocessing Wizard.
