Just completed Cobb from Hay to Wilcannia and Silver City to Warri Gate. Both now sealed all the way and the entire routes-except for a few soft spots South of Ivanhoe, in excellent shape. There is one grid about 8km from Tibooburra which is quite dangerous with a 'speed hump' on either side: dead slow recommended. The grid is either the last or second last on that stretch just as the old sealed section starts. Spoke to an RMS road supervisor who reported that the graded roads from Silver City Hwy, East to White Cliffs, are in good shape. He was heading to Tibooburra told him about the grid in question.
