The Msikaba bridge is a cable-stayed steel deck bridge, currently under construction, spanning the Msikaba River, near Lusisiki in the Eastern Cape of South Africa. The Msikaba bridge forms part of the N2 Wild Coast road (N2WC) project, which aims to improve the travel time between Durban and East London for heavy freight vehicles. the bridge when complete will have a main span of 580m supported from a pair of 127m-tall pylons. The deck will be 194m above the valley floor, making it the third-highest bridge in Africa.

GeoAfrika Surveys have two primary roles on the project site. Firstly we undertake monthly drone imagery and video capture for monitoring of construction progress. Imagery is captured in oblique and geo-referenced orthophoto formats for comparison to design. Imagery is streamed to the project team via cloud-based application. Secondly, we maintain construction oversight for the engineering consultants on the site through the placement of a highly-qualified surveyor on site.
