Réseau Ferré de France – Reopening of Avignon Sorgues – Carpentras line

Project Management : Reopening of Avignon Sorgues – Carpentras line

1 mo AVIGNON SORGUES

The French railway network RFF wished to modernise the railway line located in the department of Vaucluse and connecting Sorgues to Carpentras. This 16-km line will eventually link Carpentras and the fast speed TGV train station at Avignon.

The main objectives of the task are:

  • To reinstate the line’s original rail speed,
  • To sustainably maintain the line in use.

 The study looked at various single-span concrete or stone structures with modest apertures (approximately 1 m to 20 m) and at old-generation metal decks.
