LINCOLN -- If you've ever driven into the sunset, you know there's a point where it's nearly impossible to see. The setting sun PLUS a power outage knocking out traffic lights contributed to a three vehicle accident Thursday evening at 66th and O. Traffic lights worked only intermittently, so temporary stop signs were in place, but they were difficult to see. Three people went to the hospital with what were considered to be non-life threatening injuries. Power was restored to that area of east Lincoln by 7pm Thursday.
