Bridges and Viaducts

Bowstring-arch bridge spanning the Naviglio Grande canal: Turin-Milan section
This structure recreates the classic shape of tied-arch bridges, which have been a staple in rail engineering since the early days. 
It features a 60 m span and is made up of two opencast steel arches with H-beams on vertical and parallel planes, at intervals of 14.70 m; the keystone rise is 12 m.
The deck consists of a grille of sleepers and longitudinal ties and has an overall width of 15.60 m.

Cable-stayed bridge spanning the Po river: Milan-Bologna section
The cable-stayed bridge across the river Po features a central span of 192 m and two shore spans of 104 m. Overall, it has 92 stays of differing length and inclination. The deck consists of a continuous beam with fixed support on one tower and sliding supports on the other tower and on the shore piers. The beam-launched deck has a constant suspension height in the central span of 4.70 m. Its overall length is 15.70 m. The towers are 60 m high, rising 51 m over the deck itself.

Metal bridge spanning the A14 motorway: Bologna-Venice line
This through arch bridge featuring a triangular frame structure closed at the top, with a curved dual-track metal girder, weighs 840 tonnes and has 14 spans 5,382 m long. The new railway junction intersects the A14 motorway at an angle of roughly 35°. The sharp angle and need to keep a ground clearance of 58 m from the motorway route, without placing posts on the road surface, led to a design choice of a main metalwork girder with a 75.35 m span. The deck is oblique and was designed to allow a maximum speed of 160 km/h.   Watch the Video

Bowstring-arch bridge spanning the Sieve river: Bologna-Florence section
The limited height between the top of rail and the river convinced designers to opt for the classic tied-arch bridge solution. This bridge has a 75 m span and is made up of two steel box-section arches on two upward converging oblique planes and a mixed steel and concrete deck; the box-section ties are always inspectionable. The supports have been spaced 75 m apart; the rise is 16 m and the maximum width of the bridge is roughly 19 m.

Multiple-arch viaduct at Caivano: Rome-Naples section
Inspired by the traditional multiple-arch viaducts of the century-old Italian rail engineering tradition, this viaduct is about 2,400 m long and consists of 74 bell-shaped reinforced concrete arches arranged in 2 parallel lines and spaced 8.40 m apart. It is a continuous bearing surface for the railway superstructure. Each single arch has a 33 m chord and a 7 m rise. The bridge was designed to  accommodate the needs of the surrounding landscape and the ancient Bourbon Regi Lagni canals.

Zezely Bridge over the river Danube: city of Novi Sad in Serbia
This new double-arch steel bridge will be 470 m long and will restore full road and rail traffic between the city of Novi Sad and the opposite bank where the renowned Petrovaradin fortress is situated. Italferr has been appointed to carry out the preliminary design and executive project for the Zezely Bridge over the Danube, to be built over the top of the old bridge which was destroyed by bombings. It is also in charge of putting together the tender documentation for the assignment of contracts for works construction.
Bridge over the Euphrates River: railway line to Tabeje-al Bookamal in Syria
The metal part of the bridge is made up of 5 tied-arch articulated metal spans closed at the top.
The articulated structures are trackwork type with direct fastenings.
The alignment has been set up for single tracks, but the entire structure (piers and abutments) have been specially designed to accommodate dual tracks at some future date,
