Ponte della Costituzione

Ponte della Costituzione. Ponte della Costituzione.

The Ponte della Costituzione is the fourth bridge over the Grand Canal in Venice, Italy. It was designed by Santiago Calatrava, and was moved into place in 2007 (connecting Stazione di Santa Lucia to Piazzale Roma), amid protest by politicians and the general public. The bridge was installed in 2008 and the bridge was known as Quarto Ponte sul Canal Grande before the official name was adopted to celebrate the 60th anniversary of the Italian constitution in 2008.

In June 1999, the Municipality of Venice drafted a preliminary plan for a fourth bridge over the Grand Canal. Using a public selection process, they commissioned Santiago Calatrava in November 1999 to design the new bridge. Calatrava's response was an arched bridge with a large radius which was designed to be constructed off-site and installed entirely from the canal. The bridge is situated at an strategic point, connecting the railway station (Stazione Santa Lucia), on the north with the Piazzale Roma (the City's arrival point by car/bus), on the south side of the Grand Canal. The bridge is important both functionally and symbolically, connecting arriving visitors to the city and welcoming them to Venice with a panoramic view of the Grand Canal.

Calatrava designed an arched truss bridge with a radius of 180 metres (590 ft), with a central arch, two side arches and two lower arches. Girders placed perpendicular to the arches join them together. The girders consist of steel tubes and plates, which form closed section boxes. The stairway on the bridge is paved with pietra d'Istria[1], a stone traditionally used in Venice, alternating with tempered glass steps illuminated from below by fluorescent lights. The parapet is also tempered glass, terminating in a bronze handrail with concealed lighting. The internal structure can be appreciated by looking at a cross-section of the bridge exhibited outside at the waterfront, located between the Railway Directorate Headquarters and the Santa Lucia railway station. After fabrication, the bridge was moved into place by a large barge (connecting Stazione di Santa Lucia to Piazzale Roma) in July 2007.

Costituzione bridge

The bridge has received heated criticism and seen inauguration delays and walk-outs, which originated from three main grievances: the lack of wheelchair access, lack of necessity and its modernist-minimalist style being incompatible with Venice's decorative medieval architecture.

Ponte di Calatrava has many steps embedded in its relatively steep pavement, which means elderly people have difficulty climbing it and wheelchair users are excluded from crossing. Due to lasting protests, a mobility lift system resembling cocoons will be eventually installed in 2010, incurring large costs, since it was not part of the original design. The official budget for the project was €6.7 million, but actual costs have escalated significantly.

The placement of a new bridge a mere stone-throw from the existing Ponte degli Scalzi bridge has also proven controversial, since the distances between Scalzi and Rialto Bridges or between the Rialto and Ponte dell'Accademia bridges are severalfold longer, and with no other way to cross the canal besides the waterbus (Italian: vaporetto), or commuter gondola (Italian: traghetto). There is also no permanent connection between Venice and the well-populated Giudecca island, although a tunnel has been proposed at not much greater cost than a bridge, promising better access for tourists and residents.

The construction of the Spanish architect Santiago Calatrava will connect the Santa Lucia train station with the Piazzale Roma parking, thus uniting the only area of the city accessible by car and tie to the mainland of the lagoon city, Venice, in the region of Veneto, Italy.
