Single-Lane 		2019 From the City of Fort Bragg: "The City installed a small neighborhood traffic calming circle in about 2012 on E Fir Street at N Harrison Street. Unfortunately, due to many years of complaints as well as traffic collision increases at the intersection, the roundabout was removed in 2019. It is still shown in Google Maps but it is removed now and replaced with at 4-way stop intersection."
