The South African National Roads Agency Limited (Sanral), as part of the upgrade of the N3 from Cato Ridge to Dardanelles Cutting to an eight-lane carriageway, will implement rolling closures on the N3 national roads in both directions between the Umlaas road interchange and Cato Ridge interchange to minimise the delay of the traffic on the N3 national road during blasting. The blasting will be carried out on Tuesday, July 12, at 11:00, and on Thursday, July 14, at 11:00 should a second blast be required. All closures shall immediately be removed, as soon as the site of blasting has been declared safe, Sanral said on July 6.
