The new high speed TURIN - MILAN line

The route
• the viaduct Dora: of 1.410 metres is the longest river viaduct on the route. It consists of 39 spans,
35 of which constructed with double girder structurework in reinforced concrete and two in concrete and steel each with a surface area of 75 metres, placed in the river bed;
• the viaduct Chivasso-Aosta: with a length of 980 metres comprises 28 spans, each of 35 metres and
enables the new high speed line to cross the provincial road for Montanaro and the existing
Chivasso-Aosta line;
• the viaduct Santhià: of 3.782 metres is the longest on the route. Made up of 152 spans each of
the length of approx. 25 metres, enables the line to cross the A4 motorway junction A4 - A5 of
Mont Blanc;
The new high speed
TURIN - MILAN line
• the viaduct Ticino: 1.178 metres long, to cross the river of the same name, will be constructed in
concrete and steel with 10 spans to avoid restricting the bed section;
• the bored/cut-and-cover tunnel passing under the motorway A4 extends for 1.5 km and is the longest of the entire line. It will be built with a structure in reinforced concrete.

The new line runs approx. 125 km and starts
in the vicinity of the station of Torino Stura to
finish shortly before the station of MilanCertosa. The route runs closely alongside the
A4 Turin-Milan motorway through to the
municipality of Sedriano. Here it crosses the
A4, runs along the north side of the
motorway for about 3 km as far as the
municipality of Rho. The line then deviates
sharply north-east away from the motorway and after a wide curve to the south-east,
re-joins the existing Turin-Milan rail line to
enter the junction of Milan.
The mainly flat landscape crossed by the lines
leads to much interference with existing
roadways, with the consequent demolition
Vercelli - Interconnection of Vercelli
and reconstruction of virtually all current
overpasses and branches of the motorway. Most of the line extends along embankments. The
geographical characteristics of the area of land concerned do not represent a problem to introduction
of the new line. In fact the route exploits the natural lie of the land and runs alongside the motorway
to minimise environmental impact without causing other interference on the land.
The choice to insert the line within a corridor with an already dense infrastructure has led to the need to
deal with a number of interferences of the new line with the rail and motorway network, as well as the
water network. The works will contribute to the upgrading and improvement of the infrastructure in an
area of the country subject to intense productive traffic. The interventions envisaged regard: the road
network (motorway junctions, overpasses, toll gates, service stations), with water network
(implementation of hydraulic underground routes, optimisation of connected network) and the
upgrading of the corridor (environmental mitigation, extension of viaducts in the areas crossing rivers, to
guarantee maximum transfer in the event of high waters, construction of roads for civil protection
services etc.). The structural integration with the existing rail line will be by means of five
interconnections: two terminals at Settimo Torinese and Milano Certosa and three intermediate
ones at Santhià (Vercellese ovest), Novara ovest and Novara est. The interconnections will also
serve to route passenger trains on the historical line and freight trains on other itineraries.

The project involves construction of about 285
works, including 28 viaducts and 30 cut-andcover tunnels. The main works include:

• the interconnection of Settimo/Stura where
six tracks meet: two for the new high speed
line, two for the existing line and two for
the new rail line;
• the cut-and-cover tunnel of Rondissone: of
1,435 metres is the longest tunnel of this
type on the route. The work has great value
in terms of the landscape as it avoids any
interruption to the continuity of the territory
crossed in the vicinity of the Dora Baltea;
