CULVERT JACKED BENEATH RAILROAD AND HIGHWAY TO AVOID DISRUPTING TRAFFIC

To avoid disruption of the trunk line of the South African Railways through Durban, a contractor jacked sections of a 26-foot wide box-shaped concrete culvert through the railroad embankment and three highway ramps. This 525-foot storm water culvert is to drain sections of the eight-track rail line and a park which often are inundated by heavy rains. A jacking project of these dimensions had never been attempted in Africa before. Among the problems were the presence of groundwater since the culvert is in sandy clay about a foot below sea level and its top is only about 2 feet below the track. It was also necessary to stabilize unconsolidated earth at one point in the operation.
