Flyovers

Utilising standard Unibridge^® components a flyover can be constructed over existing roads or junctions. Supported on either concrete or steel piers, the Unibridge^® flyover system is quick to manufacture, deliver and install.

The flyover is supplied with a steel deck with anti-skid system. Unibridge^® has been pre-designed against a range of international loads e.g. Eurocodes, Australian Standards, AASHTO, British Standards and Australian Standards. The bridge is designed for a 100 year life span and 1,000,000 fatigue cycles of the appropriate Eurocode vehicle. Parapets are provided which are designed in accordance with EN 1317 type H2 and vehicular collision with the parapets will not induce failure to the structural members of the Unibridge^®.

Unibridge^® is protected against corrosion by painting or galvanising. The main structural elements of the Unibridge^® i.e. prefabricated girders, are painted with a 3-layer zinc epoxy system, and other bridge components are galvanised in accordance with ISO 1461.
