Pic 4 Left: positioning of the bridge in respect of the built-up area. The purple color shows an area which will become a
park and is connected to a green area in the centre of Mirano through the passage under the new bridge. Right: section,
planimetry and prospects.
2) Description of the territorial context.
Shape: the context is a level district mainly agricultural where some industrial areas stand out. The bridge is
near the banks of Taglio Channel, which connects Mirano and Marano.
Function: Taglio Channel is an old good transport infrastructure waterway: a channel that, because of
functional needs and due to the flatness of the district (Pianura Padana) crosses the territory with a linearity
that is the most constant and recognizable feature in such context. On one of its banks there is the road
which connects Mirano and Mira, on the other there is a cycle-pedestrian way which is used to the utmost by
the local people to go for walks.
Meaning: the historical value of the channel, besides the fact that it has turned into a place where people
spend lot of time at, has assumed a collective identity which will be surely menaced by the impact the visitors
will produce in such context.
3)Description of the work and possible alternative solutions
Shape: the bridge is 80m length. It has three bays, two side ones of 30m. and a central one of 40m., it is
35m. wide , with two carriageways, each of three lanes. It has an almost entirely steel structure, with glass
sound proofing barriers and its characteristic is the built on the Taglio banks, making it not too high. In
addition, the road continuity of Left Taglio and the cycle-way of Right Taglio have been kept, making them
pass along the banks to go under the bridge. The bridge fabricated in metal, with the front made by a series
of inclined bars with the function of hardening the core of the longitudinal girder.
Function: the bridge has a double function. The main one is the continuity of the “Passante di Mestre” with
the crossing of Taglio Channel; the second one is the continuity of the road which goes along the Taglio
