Light Rail Train Bridge
Santiago Calatrava
Jerusalem, Israel
The Light Rail Train Bridge is located near the Eastern Gate to the old City of Jerusalem, considered as the "modern entrance" to the city.
In ancient times this road connected the old city of Jerusalem
with the Tel Aviv Highway, Jaffo at the Mediterranean Sea, and
Herzl Boulevard, one of the most important arteries of the new city
of Jerusalem.

Calatrava designed this cable-stayed bridge with a single inclined
pylon that creates a clear visual direction towards the city. The
cables are arranged in a parabolic shape which develops
three-dimensionally in space, thus amplifying the impressive visual
impact unique for this bridge. Overall the strings and form of this
structure suggest a giant harp-the harp of King David as a symbol
of the holy city-inspiring city residents to call it the "Bridge of
Strings."

Architect's Statement
The Jerusalem light rail train bridge project started with the
idea that we have to do a very light and very transparent bridge,
which should span a major new plaza at the entry to Jerusalem.
These were the elements I got from the client. Ehud Olmert, who was
the Mayor of Jerusalem at that time, challenged me in this way. He
said, "Jerusalem is one of the oldest cities in the world." So I
had to make one of the most beautiful bridges.
Uri Shetrit, the city engineer, who is also an architect, was
preoccupied with how to make this area more urban, how to make it
more pleasant for pedestrians, because the traffic is enormous
there. The bus station is not far away, and many of the cars
arriving in Jerusalem have to pass through this intersection. We
wanted to unify the area and give it character. So the bridge is a
link for the tramway and for pedestrians, but it is also the excuse
to create a major plaza, to give character and unity to this
delicate place which is the entrance to Jerusalem.
My first drawings for the bridge were very abstract, and focused
on reconciling the curved plan of the bridge with the elevation,
and its articulation with the surroundings. I gave that a lot of
importance. Also, because I wanted to make the bridge so
transparent, and the mast so thin, the major impression of the
bridge comes from the cables. In the end, the form of the bridge
came to resemble a musical instrument, with the cables as the
strings. The idea of the bridge as a harp seems to me to be very
beautiful in this case. I thought the City of David deserves a
bridge that looks like a harp, which was the instrument he
played.
The S-shape of the bridge is a result of the technical
requirements of the light rail system. Its geometry is precisely
defined by the need of the tramway to go from Yaffo Street through
the plaza and into Theodore Herzl Avenue. The curve and then the
countercurve were dictated not only by the course of the tramway
but also by the speed of the trains and the degree of curve they
can pass through.
In a bridge, the formal composition and the structural solution
come together. Most bridges today are very minimalist, because we
have taken away the decorative elements that were used in bridges
since ancient times. You have very few elements to work with. The
most defining element-the one that belongs most to the physical
nature of a bridge-is the statical system, how the bridge behaves.
Also I think the reference to the site is very important; and the
way the bridge touches the ground is fundamental. Finally, there is
the way people move around and use the bridge to articulate the
city. These are the basic issues I always look at. For this bridge
in Jerusalem, the quality of life and the quality of the city-to be
responsive to the place-is the most important thing.
Bridges are instruments of peace. They join places that were
separated. They permit people to meet. They even are meeting
points. They are done for the sake of progress and for the average
citizen. They even have a religious dimension. The word religious
comes from Latin, meaning "creating a link." This particular
understanding has a very deep meaning, especially in Jerusalem,
which contains in its name the words shalom, salaam, peace. A
bridge makes a lot of sense in a city like Jerusalem.
