Yep, Nav seems to be on the ball. The H'way South to Coffs is open to all traffic, & as far as I know the Summerland Way to Casino & Lismore is also open. There has been a heap of traffic diverted through Grafton. The line up of trucks streched from the top of Junction Hill out to just short of the Mountain Veiw turnoff.I heard the Southern approach to Grafton was worse.
