Title: Exits on Washington State Interstates

Geospatial_Data_Presentation_Form: vector digital data

Description:

Abstract:

This dataset identifies exits along interstate routes in Washington State. Please direct questions about this dataset to: TransportationGISDataSteward@wsdot.wa.gov.

Purpose:

This dataset provides point locations based on the Washington State Department of Transportations (WSDOT) 24k LRS routing layer. These points mark the beginning of exit ramps on interstates in WA and provide information about where the ramp exits from and to along with the exit number where available.
