Questions to Bernard Cathelain Can you give us a quick overview of the current

status of work on the Grand Paris Express?

All the lines falling under the programme

management remit of Société du Grand Paris are

now under construction. Civil engineering has started

on line 18. And in December we awarded the contract

for the construction of the viaduct between Palaiseau

and the CEA Saint-Aubin turnback siding. We are

starting the underground work on line 17, which held

the naming ceremony for Florence, its first tunnel

boring machine, last September. This line, the

northern section of which links Le Bourget RER to

Mesnil-Amelot via Val-d’Oise and the Roissy-Charles

de Gaulle Airport complex, is particularly strategic.

It will offer a real alternative to the growing road

congestion in Paris’s northern corridor. On line 16,

where we are also aware of the specific challenges of

opening up lower-income areas of the region such

as Clichy-Montfermeil, work is ramping up, and six

tunnel boring machines have already been deployed.

At Aulnay, the first buildings for the future operations

centre for Lines 16 and 17 are being built. Finally,

for the southern section of line 15, between

Noisy-Champs and Pont de Sèvres, all structures are

now under construction, most of the station boxes

have been completed and track laying has begun,

so railway infrastructure is now being installed.

I would also like to recognise the progress made at

the worksites for line 14, between Olympiades and

Orly, where the Paris Metro Authority (RATP) has now

taken over as programme manager.
