Structural type
Langer beam
The existing road in the area of the White Water Creek sinkhole has been heavily disturbed in the past by slope shifts and rockfall. The new bridge replacing a temporary bridge has been constructed to span the entire unstable area of this natural phenomenon. Its span ensures that the bridge's micropile foundation is located in areas that are no longer affected by these phenomena. The bridge deck is supported by two main longitudinal beams of I-shaped cross-section, which are interconnected by a system of cross-beams. The bridge deck is composed of a composite reinforced concrete slab, supported by the cross-beams. The main longitudinal beams are stiffened by two planes of arches formed by a box section embedded into the beams above bearings. The bridge was awarded the 2014 Bridge Work of the Year award from the Ministry of Transport.
