Abstract (en)

[origin: EP0424223A1] Process and device permitting doubling of the flow on the lanes bordering the central reserve of motorways, comprising a minimum of 3 lanes in each direction, causing no disturbance of the traffic for the duration of the works. The assembly consists of a chain of prefabricated elements, assembled mechanically or by means of reinforced concrete, prestressed or otherwise. The installation works may commence without land acquisitions and without prior foundation works. The dimensions of the elements as well as the design of the installation machine permit execution of the installation works while always leaving the lanes adjacent to the lanes in question free and hindering the latter only during the peak hours of traffic chosen for carrying out installation of the elements. The changing of lanes is possible on both levels. <IMAGE>
