BRIDGES THAT ARE SLID IN PLACE UNDER THE TRACK...
DES PONTS QUE L'ON GLISSE SOUS LES VOIES...
Two examples (a road tunnel under the Metz-Thionville line and an underpass for light vehicles under the Tours-Saint-Nazaire Line) are used to illustrate this new technique for building and installing tunnels under railway lines where there need be no stop to the flow of traffic; the tunnel is prefabricated alongside the track and then pushed or pulled into its final place.
