Circet has installed a pylon 65 meters tall between the highway and the French railway SNCF track.

The operation was carried out at night, under close supervision, with high pressure on safety.

It is on the edge of the French A10 highway, next to the St Arnoult tollgate south of Paris, between the SNCF track and a building, that Circet replaced a pylon more than 60 meters tall for highway concession company Cofiroute.

Circet, the prime contractor, supervised the work of specialized companies in two phases:

  1. The night-time installation of a new pylon 62.5 meters tall, with a 3-meter riser block, the entire assembly weighing nearly 16 tons.
  2. A few days later, the removal of the 69-meter pylon in place, also at night.

The project had been prepared for over a year - due to environmental challenges – and was executed successfully.
