A grade separated interchange replacing an at grade roundabout, the busiest junction in Harare. Built piece by piece. Scroll to follow the structure rise, from the bulk services beneath the ground to the day it opened.
Where an at grade roundabout once choked the city, a full grade separated interchange now carries traffic on multiple levels. This is the spine of the project, the geometry that everything else serves.
Loop and ramp systems thread traffic between levels at speed. Fresh primer is laid over a new base course, MSE retaining walls holding the embankment as the curve sweeps toward the deck.
Before the surface comes the system beneath it. Large diameter pipe is bedded in deep trenches, the drainage network that keeps the interchange working through every wet season.
A working city cannot pause. Crews relocate the bulk water main and lay reinforced concrete pipe through the footprint, sequencing every connection so supply holds while the interchange takes shape above.
Commissioned 30 May 2025. Five main bridges, two underpasses, six culverts, loops and ramps, roughly 24 km of roadworks, over 15 km of stormwater, 6 km of bulk water main relocation, MSE retaining walls and full electrical installations. A grade separated interchange built for the next generation of the city.
