There is still some repair work left to do on the Dorsey Drive overpass, after an NID water mainline break last month. And that means a 24-hour closure, starting Monday night at 6. The District says during the work there will be single lane closures on both the southbound and northbound off-ramps of the Golden Center Freeway Interchange there. There will also be no left turns allowed across the overpass to Sutton Way or Sierra College Drive. Additional traffic control will be enforced on nearby streets, as well. Water service won’t be affected.
