This is one impressive bridge. It is impressive in its statistics, engineering and visual impression.

In terms of statistics: nearly 3km in length, 57m above the water at the highest point, towers 140m high, over water up to 65m deep, 630 million euros in cost, 6 years in construction, envisioned a 100 years ago.

The enginnering is impressive also: it is designed to accomodate the sismic activity of the region, as well as the progressive widening of the gulf (30mm a year) due to tectonic activity. Likewise it is designed to handle a crash by a very large ship, and had to deal with the loose sediment of the seabed.

It's longest span is 560m, currently ranking 13th longest in the world, but when overall length supported by cable-stays is considered, the bridge ranks second in the world at 2,252m (this lengh does not include the support ramps on either side).

Visually it is quite impressive also: a fitting addition to its setting, simple, powerful lines.
