| Ferrovial-built section of the A-67 highway inaugurated  Spain's Infrastructure Minister, Magdalena Álvarez, inaugurated the Molledo-Pesquera section of the A-67 highway, which was built by Ferrovial Agromán. This 11.87-kilometre stretch of road completes the Cantabrian part of the A-67, which will connect Santander to Palencia. Construction cost 184 million euro. The highway, which will replace the N-611, will incorporate various unique structures with a view to traversing the area's complicated relief. To date 1.6 kilometres of tunnels and one cut-and-cover tunnel have been built, as well as five viaducts measuring 1.9 kilometres in total. The most noteworthy viaduct, at Montabliz, will be one of the largest structures of its kind in Spain once it is operational. Measuring 721 metres in length, it crosses the deep valley of the Bisueña River using an environmentally-friendly solution.The viaduct has a single, five-lane deck supported by four piers to minimise the bridge's footprint and visual impact. The bridge has five spans measuring 110, 155, 175, 155 and 126 metres. At its highest point, the viaduct is 150 metres above the valley floor, and the tallest pier is 140 metres high, i.e. the tallest in Spain and one of the tallest in Europe. Only a few viaducts, such as Millau in France and Europabrücke in Austria, are taller than Montabliz. write your comments about the article :: © 2008 Construction News :: home page |
