Straddling a threshold between urban bustle and the tranquillity of nature, the sweeping form of Alexandra Bridge alluringly beckons at the onlooker to cross the gateway into a sanctuary of calm repose. Rising about 15 metres above Alexandra Road, the curving deck of the bridge introduces a gradual passage of transition into the approach of the adjoining Alexandra Link. The arching steel rib armature of Alexandra Bridge asserts a structural dynamism in the day, but metamorphoses with nightfall into a dematerialised sculpture of light.
