NESCIO BRIDGE - AMSTERDAM
Crossing the Amsterdam Rijn canal, between IJburg and Amsterdam South-East a bicycle and pedestrian bridge called Nescio bridge is constructed. The total length of the bridge is 790m, whose main free span is 168 m and 9.3 m above water level.
The abutments are constructed in concrete with an expansion joint every 15 meters, while the main span is one steel structure. A combination of a cable stayed bridge and a suspension bridge forms the main support system of the bridge. The deck itself is a steel tube profile, whose height varies with the length of the bridge. Also the asymmetrical cross-section varies in the longitudinal direction. The deck consists of a 3.5-metre-wide cycle path and a 1.5 metres wide footpath. In the middle of the bridge both function are next to each other. On both sides of the channel the two functions separate and the footpath ends on a staircase. The smooth line of the bike path is tailored to the cities-architectural design plan. So the cycle path crosses the canal diagonally.
