Sioux Falls Highway Projects Near Openings, Continue Through 2027

The U.S. numbered highway system is marking its 100th anniversary, with Route 66 celebrated as a lasting part of the network and a source of community and travel memories. Elsewhere, road projects are advancing to improve access and safety: Sioux Falls expects new roadway segments to open while other work continues into 2027 and beyond, and crews in Vietnam are widening National Highway 18 to ease congestion near an industrial zone. Vietnamese lawmakers also weighed funding for three mountain expressways, warning that local matching requirements could strain poorer provinces and calling for greater central-government support. In Thanh Hoa, officials are accelerating land clearance and compensation work to keep key roads, including a route connecting the city with Tho Xuan Airport, on schedule.
