INTRODUCTION
The bridge, still in use, is 164 meters long, and its trolley can
transport six cars and several passengers in one and a half
minutes.
It operates every 8 minutes during the day (every hour at
night), all year round. An estimated four million passengers
and half a million vehicles use the bridge annually.
There are two new visitor lifts installed in the 50 meter high
pillars of the bridge that allow walking over the bridge's
platform, from where there is a superb view of the port and
the Abra bay. Of course is not free.

HISTORY
The Bizkaia Bridge was built to connect the two banks which are
situated at the mouth of the Ibaizabal River.
It is the world's oldest transporter bridge and was built in 1893,
designed by Alberto Palacio, one of Gustave Eiffel’s disciples.
The Engineer Ferdinand Joseph Arnodin was in charge, and it was
the solution given by the engineer to the problem of connecting
the towns of Portugalete and Getxo without disrupting the
maritime traffic of the Port of Bilbao and without having to build
a massive structure with long ramps, otherwise are 20km by car.
Palacio wanted to design a bridge which could transport
passengers and cargo, and that could allow ships to go through.
The service was only interrupted once, for four years, during
the Spanish Civil War, when the upper section was dynamited.
From his house in Portugalete, Palacio saw his masterpiece
partially destroyed just before his own death.
On 1939-1941 it was rebuilt.
HISTORY
In 1999 important works were done on the bridge, including
the installation of elevators in the towers of both banks and
enabling a walkway on the upper beam, in order to
introduce a tourist use.
On July 13, 2006, the Vizcaya Bridge was declared
a World Heritage Site by UNESCO
At first, was painted black, however, a restoration project
that includes a color change was approved in 2010. Three
tones were proposed, similar to the three iron ore next to
this place:
-The ‘Campanil’ from Gallarta, the ‘Blenda’ from Triano
and ‘Vena roja hematita’ from Somorrostro. Finally was
elected the one from Somorrostro.
