Lighting in Design Q1 2024

In both instances, the luminaires are concealed in carefully – almost surgically – sculpted niches within the extruded profiles. Facing the traffic, a sharp blue light near the top of the post casts a dramatic wash down the length of the triangulated post, reflecting on the bi-coloured surfaces of its blue and yellow neighbours, illuminates the horiz ontal line of the ex isting corten truss, then finally creates a blue curtain on the road below.” T he second luminaire is concealed near the base of the post on the pedestrian side, casting a warm golden glow from inside its carved concave casement, illuminating the ground surface for safe night-time passage across the bridge. R esidual hints of blue and yellow flicker as pedestrians pass by. “ C ollectively, both lighting types form a series of parallel lines – one touches the highveld sk y as pin-prick s of blue, and the other a k nee-high trail of golden sq uares. . . and into the pragmatic function of each, a variation of unex pected moments emerge from the meeting of shadows, reflections, solid and void, ” ex plains O tten. T he bridge itself is ex perienced in several contrasting ways – pedestrian & vehicular, day & night, north & south – each determined by a unique combination of characteristics such as colour, light,

detail, with each face being rendered in a different, carefully selected finish. Acknowledging the colour palette developed for the W its-1 0 0 campaign, hues of blue and yellow were selected for the two outer traffic-facing faces, with the inner pedestrian facing surface being rendered in a warm charcoal matt. “ W ith careful placement and alignment, the triangular plan of the post enables a tight spacing between posts on the pedestrian edge that open more generously towards the vehicular side, heightening spatial depth and visual drama, ” adds the lead architect.
