Watch out for overnight road closures on the Great North Rd interchange. The closures, which are necessary for works related to the Waterview Connection project, will take place from July 5 to July 30 between 11pm and 5am. They will enable the giant concrete Super T beams to be lowered into place. The beams, which form the base for the roadway, are being placed on a section of Ramp 4, the highest of the interchange’s four bridges. The closures affect people travelling on Great North Rd towards Pt Chevalier, motorists who want to join the Northwestern Motorway city-bound; or who want to use the Northwestern exit at the interchange, together with those coming from the Carrington Rd and Pt Chevalier intersection. Detours will be in place.
