I've just done a return trip to Whyalla from Peterborough. 4th January until 15th February 2012. Road works a couple k's from Wilmington. Speed resticted to 80kph unless sign posted lower. Work involves shoulder width expansion and that means lots of trucks hauling gravel. Watch out for gravel on the road mainly where they are working. Wasn't too bad yesterday but some corners had gravel in centre of lane. Had to follow a couple tippers going down, was ok but had to keep distance to avoid getting hit with gravel thrown up by rear wheels.
