One of the roundabouts is at a crossroads known as the Intersection of Death, where pedestrians and bicyclists frequently experienced conflicts.
Although the roundabouts had been in Stanford's plan for about 2 years, the university's marching band tested the idea in fall 2006. The band built a roundabout in front of Stanford's landmark clock tower to help improve traffic flow during the week of the big game with crosstown football rival the University of California, Berkeley. Band members adorned the circle with a sculpture and decorations.
The LSJUMB-constructed roundabout was up for a year before it was replaced by an official one.
