SPAIN: In Madrid, the Madrid Calle 30 project includes the redevelopment of the M30 motorway by creating direct connections to the main routes through a great number of tunnels. Besides, the infrastructure around the M30 is being significantly improved and modernized and new green zones for recreation and leisure are being created. The building project, consisting of 15 different stages, was started in September 2004 and is planned for completion early in 2007. The jobsites cover a length of 99 km, 56 km of which are tunnels. Working on the project are up to 100 Liebherr cranes, the majority in the HR series. The machines are used for installing reinforcement cages into the slurry excavations, for concreting, placing joints into the trenches, loading and unloading vehicles, machine assemby and the like. An additional 50 Liebherr cranes are working in Madrid on various jobsites, representing the highest concentration of Liebherr crawler cranes in the world, according to the manufacturer.
