The oldest bridge in Latvia - Kuldīgas tilts, situated in pretty little town Kuldīga. With 164 metres it is the longest bricked bridge in Europe. It is built in 1874 .

Czech examples:



Nuselský most (Prague)
Nuselsky most is a viaduct, I saw it when I was visiting Prague in 2004. Intresting thing in this viaduct is that in the inside of the superstructure undergrund trains passes through. (superstructure is a box section).

^^ Looks just like the Vasco da Gama. Where is it supposed to connect to land?
Yes, they are similar... you can see the differences with these two photos:



The Vasco da Gama bridge carries six road lanes.
The new one (Portuguese techinical name TTT) will allow six road lanes, and 4 rail tracks (two for conventional trains, and two for TGV/High Speed trains).

In Lisbon, the TTT will end near Chelas district allowing the bridge to be connected with the local road/train systems. On the other side of the river the bridge will end in the city of Barreiro. it is part of the Madrid-Lisbon new high speed train line.

And now, some pictures from Porto, Portugal!



Arrábida bridge

The Arrábida Bridge is an arch bridge over the Douro River that connects Porto to Vila Nova de Gaia, in Portugal. It is the most downstream bride across the Douro River, just few kilometers from the Atlantic Ocean.
At the time of its construction in 1963, the bridge had the largest concrete span of any bridge in the world. The total length of the tray is of 615m, having a width of 27m. The arch is 52m tall and the plate rises up to 70m above water level.






D. Luíz I Bridge

The D. Luíz I Bridge is an arch bridge. At the time of construction its span of 172 m was the longest of its type in the world.
The construction was begun in 1881 and the bridge opened on 1886-10-31.
This bridge is a World Heritage Monument. The upper side of the bridge holds the yellow line of Metro do Porto.






Infante Bridge

The Infante Bridge was inaugurated in 30 March 2003 following a project by the engineer Adão da Fonseca. With a 371 metres long and 20 metres wide deck, it is a Maillart-type arch bridge, built at a high altitude level, presenting a span-rise ratio of 11,2, with a 280 m arch span – a world record, meaning that domains never entered before in this kind of bridges (considered by the world experts to be the most elegant) have now been achieved.

The bridge has two basic interacting elements: a box girder, relatively rigid, with a regular height of 4,5 m, supported by a flexible 1,50 thick arch with a 280 m span and a 25 m rise.






D. Maria Bridge

The Maria Pia bridge is a railway bridge built in 1877 by Gustave Eiffel. Built of wrought iron, its two-hinged crescent arch carries the railway line to Lisbon for 353m across the River Douro at a height of 60m.
In 1991 the bridge was superseded by the new São João Bridge.






São João Bridge

Once again the responsibility of conceiving the project of a bridge was placed upon Edgar Cardoso (also responsible for Arrábida Bridge). This time, the plan was to create a project for a railway bridge that would replace the old D. Maria Pia Bridge. This railway structure adopts a solution consisting of a portico with three spans (two measuring 125m and one of 250m), set upon majestic pillars founded at the riverbed, by each of the banks. The inauguration took place on 24 July 1991, S. João Day.





Freixo Bridge

The Freixo Bridge, a work by Professor António Reis, consists of two twin beams, set apart by 10cm throughout the whole of the extension. The bridge stands upstream of the other bridges, at the very edge of the city. The bridge has 8 spans, the main one measuring 150m. This one is followed by 115m spans on each side, which, in turn, are followed by minor ones. This bridge comprises 8 traffic lanes. It is part, along side with Arrábida Bridge, of Porto-Gaia Ring Road.

^^ thanks. A couple of questions...

* What is the length of the main span for the Arrábida Bridge?
* As the D. Maria Bridge is now superceded by the São João Bridge, what is the D. Maria Bridge used for?
