![Pedestrian bridge][1]Toronto, Ontario Canada, one of the few bridges between buildings has been realized few years ago. The elevated bridge, a sleek glass tube, interwoven with and supported by a steel structure, connect St. Michael's Hospital and the new Li Ka Shing Knowledge Institute. The bridge’s tubular steel frame, which is about 30 metres long and 4 metres in diameter, was manufactured and assembled by Gartner Steel in Germany, shipped across the Atlantic to New York and then trucked to Toronto. After being hoisted into place workers spent about six weeks the install the 65 curved glass panels specially designed and manufactured in Italy. Each panel consists of three layers -- a single 10-mm thick pane of clear tempered glass and two 8-mm panes covered with a solar film to provide shading. Each pane of glass is a curved parallelogram (as opposed to a curved rectangle) so that the joints in the glass follow the white steel structure behind them. This is a clear example of a globalize economy in the construction industry [1]: https://edxuploads.s3.amazonaws.com/14146383941320207.jpg
