November 14, 2025 – VDOT RWIS Data Update

On November 14, 2025, DEP API was updated to use SmarterRoads as the source of VDOT RWIS data in response to VDOT’s migration of RWIS stations described in November 6th announcement. The DEP development team switched the source interface in a way that preserved the DEP API output and prevented need for any rework from the downstream users. VDOT has confirmed that the element mappings and units are correct. As of November 14, 2025, VDOT RWIS data is once again available in the DEP API output.
