The new Lights Ferry Connector in Flowery Branch is now projected to open to motorists May 6, following some delays involving granite pavers at the roundabout. Officials had hoped for an April opening, but “there have been some unforeseen delays on the roundabout,” said John McHenry, Flowery Branch’s community development director. One of the issues involved “an error between the contractor and the design engineer on the pavers,” he said.
