Thanks guys appreciate the comments....
You can walk across the bridge and it is called the Millenium Bridge....
Some info.
Gateshead Millennium Bridge - the world's first and only tilting bridge!
Designed by Wilkinson & Eyre Architects and Engineers and Gifford & Partners, the bridge takes its place at the end of a line of distinguished bridges across the River Tyne, including the Tyne Bridge and Robert Stephenson's High Level Bridge.
Linking Gateshead with Newcastle via Gateshead Quays and Newcastles Quayside, the bridge not only serves a functional purpose as the River Tynes only foot and cycle bridge, but its grace and engineering attract people from all over the world.
LaFoto is right about no.4 it's not reflections but the inside of the building through the glass front.
Some facts from The Sage Gateshead regarding construction.
The spectacular curved steel roof, which weighs in at 750 tonnes, is made from 3,000 stainless steel panels and 250 glass panels. If the roof were laid flat, its 12,000 square metre area would be big enough to accommodate two football pitches.
* most of the 3,858 tonnes of steel is hidden from view in the foundations and reinforcing the walls and floors?
* more than 1,100 concrete and steel piles have been drilled into the ground to support the massive structure?
* more than 18,000 cubic metres of concrete has been poured into the foundations of the building - that concrete could fill 23 competition-size swimming pools, make almost 5 million foot-square paving slabs - enough concrete flags to build a path 800 miles long from St James' Park, Newcastle, to the San Siro Stadium in Milan - and still have enough left to pave over the pitch six times?
HTH.
Thank again for the comments.
