The aqueduct bridge over the Loing ( French pont-aqueduc du Loing ) leads the Aqueduc de la Vanne over the Loing , i.e. the approximately 156-kilometer-long aqueduct that was built by Eugène Belgrand between 1866 and 1874 to improve the water supply in Paris and is still in operation.
description
The aqueduct bridge is located on the southern edge of Moret-sur-Loing near the parallel departmental road D606, the former Route Nationale 6 with the Viaduc de Moret-sur-Loing . It crosses (from west to east) the Loing, the Canal du Loing and the Orvanne .
The 2357 m long siphon with which the aqueduct crosses the Loing valley is located on the aqueduct bridge. The siphon originally consisted of two parallel cast iron pipes with an inner diameter of 1.10 m. A third line was added later and the bridge widened accordingly. The siphon begins about 1 km east of the bridge at what is now the D606 roundabout. In the west it ends after an approximately 800 m long underground section and an iron bridge on which it crosses a lower railway line.
The bridge structure itself is 584 m long. It consists of the actual bridge over the Loing, the Canal du Loing and the Orvanne with five basket arches and clear widths of 12 + 30 + 35 + 30 + 12 m as well as a series of the same, smaller arches in the flood bed. Eugène Belgrand names 33 arcs, but over 40 small arcs are drawn in the elevations. As with the larger aqueduct bridge over the Yonne , the one over the Loing is made from béton aggloméré according to the Coignet system , i.e. from rammed concrete and also has the round arches supported by narrow panes in the arch spandrels that support the bridge panel.
