There’s an announcement today of yet another in the catalogue of Dubai’s biggest-tallest-longest developments.

The world’s longest arch bridge will be built across the Creek, with work due to start in March and completion expected in 2012.

It will be quite a landmark:

This will be the sixth bridge across the Creek, which runs through the centre of the old original city of Dubai, and is located towards the original end of the Creek (it’s being extended) near Festival City.

It will have 12 traffic lanes able to carry 20,000 vehicles an hour in each direction, will also carry a line of Dubai’s new Metro rail system, the Green Line, and will have a Metro station. It will also have an abra station, thus linking it with the Creek’s water transport.

The new bridge will be a total of 1.6 kilometres long with the arch being 607 metres long and 205 metres high.

The project also includes Creek Island, on which Dubai’s Opera House will be built and a massive road access system, with 12 kilometres of new roads and 22 intersections in the surrounding area.

Total cost is reported as AED3 billion (US$815 million).
