Leonardo bridge to be built in Texas
A bridge designed over 500 years ago by Leonardo da Vinci is at last being built. The University of Texas of the Permian Basin has announced plans to build the 220m pressed bow structure, which was originally designed to span the Golden Horn in Istanbul, Turkey. This is the second modern-day Leonardo bridge project - the first was built by the Norwegian Transport Ministry in 2001. Norwegian artist Vebjørn Sand is leader of the project.
