Roundabouts
Roundabouts are new to Billings. The only one currently in use is at King Avenue West and Olympic Drive (http://www.ci.billings.mt.us/index.asp?nid=605). Roundabouts are being installed around the United States and Canada, and have been shown to reduce the frequency and severity of accidents while helping traffic flow more smoothly. Please look through the links below for more information on roundabouts.
