Abstract
The Megadim Railway Bridge carries two railway lines over the Tel Aviv-Haifa Expressway. It has been sited near an existing single-track bridge. As there are plans to add two traffic lanes to the four-lane expressway, the existing bridge will have to be demolished, since it is too narrow. The owner required that the new bridge be constructed without any disruption to train traffic and with only minimal disruption to road traffic. In order to meet these requirements, a structural system that used 400 t prefabricated beams was employed. The prefabricated beams, among the heaviest ever used in Israel, were cast at the site, hoisted into place and installed.
