INCORRECT. But still a roundabout first.
In 1992, in Gainesville, Florida, the first roundabout to replace a traffic signal was built.
In 1992, in Santa Barbara, the first roundabout in California's state highway system was built.
And in 1996, the U.S. city that now has more roundabouts than any other—Carmel, Indiana (an Indianapolis suburb)—built its first roundabout.
The correct answer is B: In 1990, the Las Vegas suburb of Summerlin, Nevada, built the first two modern roundabouts in the United States. Both were at brand-new intersections.
CORRECT. In 1990, the Las Vegas suburb of Summerlin, Nevada, built the first two modern roundabouts in the United States. Both were at brand-new intersections.
The other answers are roundabout firsts in different ways:
- In 1992, in Gainesville, Florida, the first roundabout to replace a traffic signal was built.
- In 1992, in Santa Barbara, the first modern roundabout in California's state highway system was built.
- And in 1996, the U.S. city that now has more roundabouts than any other—Carmel, Indiana (a suburb of Indianapolis)—built its very first roundabout.
