On October 17, 2025, the DEP API event data output was updated for VDOT events to include the end mile marker values for work zones where that data is available.

In scope of these enhancements, there are additional updates that are anticipated to be deployed by early November that will include the following additions (when available) to the DEP API VDOT event data output:

• <typeFurtherInfo> freetext field for “other traffic” and “other weather” event types
• <cause> for short term weather events
• <description> for the start and end location point names and <specialFacility>  when used for special facilities
