The Washington State Department of Transportation got a visit from “royalty” this month. In one of its latest Facebook posts, WSDOT’s social media team drew inspiration from one of Netflix’s most popular shows, “Bridgerton,” which is coming out with its fourth season in 2026. That homage got some play in the comment section from Seattle-based author Julia Quinn, who wrote the books behind the series. The agency’s social media presence is renowned for its pop-culture savvy and goofy creativity. “This week, on Bridgerton …” WSDOT wrote in the Sept. 16 post, emulating the style of “Lady Whistledown,” an anonymous writer integral to the plot.
