A portion of the Oursan Trail across Briones Dam will be closed during weekdays beginning April 19 and continuing until August 29, 2022, due to large equipment working on a project in the area. Detour signs will be posted to route trail users away from the project site, along a new section of trail, and back onto the original trail tread at a point beyond the project work. The trail over Briones Dam will be open for regular trail use after 5:00 p.m. on weekdays and all day on weekends.
