The Umbogintwini River Bridge, on the N2 in KwaZulu-Natal, is part of the R50-billion upgrade programme of the N2 and N3 freeways in the province, and advanced engineering technology will in future prevent the kind of failure of concrete bars that led to its temporary closure. “The supports between the pier and the deck were built using a very old style of design. It was done in the 1960s and is not done anymore. When we upgrade this section, this will be replaced entirely,” said South African National Roads Agency Limited (Sanral) Eastern regional manager Dudley Mbambo.
