A new traffic calming device is making its debut in Helena! WTI, Bike Walk Montana, and neighborhood volunteers teamed up to install a pop-up traffic circle, which is designed to slow vehicles on a road near a popular trail head where there are many pedestrians. The circle will be in place for one month, during which time a camera will record traffic speeds and researchers will gather public feedback on potential long-term solutions. KTVH Montana posted a news report showing the installation on its website. WTI has participated in similar neighborhood traffic calming projects in Bozeman.
