The U.S. continues to warm up to traffic circles, a road design long embraced globally. Until the 1990s, circular intersections were rare, but in the past 25 years, an estimated 10,000 have been built in cities and towns across the U.S., with plenty more planned. This lags behind countries like the U.K., which has almost three times as many, despite being 40 times smaller in land mass.
