Jerusalem's new light rail needed a bridge to take the trains high above city traffic at the western entrance to the municipality. Why not also make this functional structure a work of art that evokes the city's rich history?

That was the thinking behind the String Bridge, designed by the renowned architect Santiago Calatrava. The cables reach a peak high above the street, reminding viewers of David's harp.

Watch Deputy Mayor Naomi Tsur and city architect Ofer Manor describe how the light-rail bridge has become "a new part of Jerusalem, which is trying to do its best to show respect to the past that we are firmly rooted in but also takes us forward into a new century of modern infrastructure and transport."
