R oyal HaskoningDHV was appointed by eThekwini Bridge. The geometric design of the interchange was carried out by eThekwini Municipality. The Cornubia Boulevard Bridge was required to accommodate the Cornubia Boulevard Cross Road across the N2/26 to link the town centres of Umhlanga Ridge and Cornubia. The bridge was designed to accommodate eight lanes with two pedes- trian sidewalks. It crosses the N2/26 at km 4,65 at a skew of 13,5° to the centre- line of the N2/26, and is 125 m long. Span 1 to the west crosses a ramp from the N2, which loops to the west and back to join Cornubia Boulevard Cross Road Municipality for the design and construction monitoring of the Cornubia Boulevard

to the north, providing access for traffic on the North Bound Carriageway (NBC) across the N2 towards Umhlanga Ridge. Spans 2 and 3 cross the NBC and SBC of the N2/2 respectively. The deck is a three single cell box girder, cast in three stages longitudinally and transversely. The deck depth is 2.1 m and the width varies from 34 m to 43 m. To accommodate this varying deck width the bottom of the box was varied from 5,1 m to 7,6 m while the cantilevers width was kept constant. The bridge also accommodates the Bus Rapid Transit (BRT) lanes. The BRT projects are being rolled out across South Africa in 13 cities as part of a national co-ordinated public transport programme. The BRT lanes across the Cornubia Bou- levard Bridge form part of the GO!Durban BRT project. z
