Authorities say one person was killed and two others injured in a 2-vehicle crash Saturday on the U.S. Highway 52 Savanna-Sabula Bridge. 61 year old Gregg O’Bryant of Sabula was taken to Jackson County Regional Health Center in Maquoketa, where he was pronounced dead. 63 year old John Ritchie and a passenger, 60 year old Beth Ritchie, both of Savanna, were taken by ambulance to MercyOne Clinton Medical Center for treatment of their injuries. According to the Iowa State Patrol, O’Bryant was traveling west on the bridge Saturday night when his vehicle traveled to the right and struck a guardrail. O’Bryant then overcorrected into the path of Ritchie’s vehicle, causing a collision. The accident remains under investigation.
