The Gotthard Transalpine
Railway also known as the AlpTransit Project, represent one of the
greatest engineering and
infrastructural challenges of modern age. The new railway line begins
about 80 km north of Milan and links Lugano with Zurich, allows to
cross Alps throughout the Gotthard Base Tunnel, the longest tunnel in
the world of a length of 57 km, and Ceneri Base Tunnel which will be
into service in 2020.
The project, which involved
seventeen years of work and 11 billion euros, is situated in one
of the main hubs for European
rail traffic and is intended to transfer cargo transportation from
road to railway as well as reduce traffic on road lines.
Looking at this, a consulting
architectural group studied and designed all the structural elements
and of all the landscape modifications in order to confer a coherent
and unified architectural image with the Gotthard motorway network
accomplished thirty years previously.
In order to minimize the
impact that the construction of a large infrastructure project would
have on extensive territory areas, the project management of
AlpTransit, owner of the work, undertook measures of compensation
consisting both of small and large-scale interventions.

interventions
included the Claus Lake,
located 800m above the tunnel elevation, which was created on a fill
made with excavation material from the intermediate access shaft of
Sedrun.
While, a significant
large-scale intervention was the shifting of the historical railway
line of village of Pollegio along the motorway. This has allowed to
reunite the historic village centre with its original surrounding
lands after a separation of over a century.
The project established itself
as an excellence model, due to defined ambitious aims for the
excavation management which produced over 24 million tons of material
extracted from the Gotthard Tunnel.
Excavated materials were
managed due to favouring the reuse as much as possible. For this
purpose, were performed
solutions for the production of aggregates for concrete and for
long-term stockpiling of left-over material by ensuring an optimal
economic operation and the minimum environmental impact.
