The West Virginia Department of Transportation (WVDOT) supports free data exchange with other organizations and the general public.
The GIS data is published in ESRI shapefile format and compressed as ZIP files. Some of the data is also published as web services. The spatial reference for the data is Universal Transverse Mercator (UTM), Zone 17, and North American Datum (NAD) 83.

LRS Road Network Data
The WVDOT linear referencing system (LRS) contains multiple linear referencing methods (LRMs) by which events (assets or activities) are recorded against a location in the agency’s highway network.
The LRS road network data here is developed based on the Countywide Milepoint LRM. Per the LRM, Interstates are set up as continuous routes across county boundaries and their mile points are not reset at county boundaries. However, such a route has a unique Route ID in each county that it crosses; and for all the other routes, belonging to various other sign systems, their Start / End mile points are reset at county boundaries. For more detail on the WVDOT Countywide Milepoint LRM, please refer to the documents below.
Please keep in mind:
- Only the routes maintained by the WVDOT Division of Highways are included in the data published here.
- Only dominant route data is published. The general rule for route dominancy is: among all the concurrent routes the route with the lowest sign system code dominates. If more than one route shares the same lowest sign system code the one with the smallest route number dominates.
- Measures embedded in routes are derived by linear interpolation based on calibration point data collected by using a Distance Measuring Instrument (DMI) except for ramps whose measures are derived based on geometry length.
- The LRS network data is published once a quarter. The current LRS road network data is as of September 2017.
