Notes
5th leg is on-ramp to SR 240. Opened November 2007. Lane configuration reduced in 2016. Modified in 2018 to add metering signal. According to local news (link below) they started metering the traffic on the westbound Columbia Park Trail approach in 2018. It only turns on when traffic coming off the freeway gets backed up. https://97rockonline.com/tri-cities-roundabout-gets-new-metered-traffic-light-wait-what/ 21442
