Sometime earlier this year, VDOT began migrating RWIS stations from the system that DEP was using to collect RWIS data to another system and the new SmarterRoads portal. The result of this migration was that DEP was slowly losing access to RWIS stations. Once notified of this migration, the DEP team has prioritized addressing this change and using the new interface for VDOT RWIS data. While the source data format is different, the DEP will strive to maintain the existing API output and reduce or eliminate any changes needed for the downstream API users. It is anticipated that the DEP change will be in place on or around November 14, 2025, at which time all VDOT RWIS stations’ data will once again be available to the DEP API users.
