Webuild and NGE completed the excavation of a tunnel of Paris Line 16 of Grand Paris Express after the TBM Mireille ended its journey with breakthrough in shaft at Mare au Chanvre site in municipality of Sevran. Thus, the TBM Mireille completed half of excavation of tunnel for section of the metro line in northern-eastern Paris.
The breakthrough by TBM Mireille completed the first 5.3 km of the tunnel work connecting Chelles with the municipality of Sevran, resulting in approximately 83 percent of the work on Lot 2 being complete.
TBM Mireille broke through the wall of the shaft at the Mare au Chanvre work site in Sevran, the first of two TBMs working on the section of the line – known as Lot 2 – to complete its journey. After having started at the south end at the Bel-Air site in Chelles, the TBM Mireille will be dismantled and its parts removed from the shaft in preparation for the arrival of “Houda”, the second TBM, which has excavated approximately 4 km of a total of 5.8 kilometres. It is expected to arrive in the autumn.
The works for the construction of Line 16 of the Grand Paris Express Lot 2, started in January 2019, and includes the excavation of 11.1 km of tunnels with two TBMs and the construction of four stations – the Aulnay-sous-Bois, Sevran-Beaudottes, Sevran-Livry and Clichy-Montfermeil stations.
Webuild and NGE are developing 11 out of a total of 29 km of tunnels for Paris Line 16. They are also to build four of the 10 stations to be located along the line. The entire line will serve the Paris department of Seine-Saint-Denis, within which are 16 municipalities.
EUR 5.3 billion is the value of the construction of Line 16 part of the Grand Paris Express project and will provide connections from Saint-Denis Pleyel to Noisy – Champs in less than 30 minutes. The new line will share a 6.4 km tunnel with metro Line 17, connecting the Saint-Denis Pleyel, La Courneuve Six-Routes and Le Bourget RER stations, as well as the operations center located in the municipalities of Aulnay-sous -Wood and Gonesse.
It will serve cities that are currently poorly provided with public transport, such as Clichy-sous-Bois or Montfermeil, as well as the Descartes university campus located in Champs-sur-Marne and Noisy-Champs, and the business area of the Saint-Denis plain.
The line is expected to become operational in 2026 when trains will be transport an estimated 200,000 passengers every day, taking 154,000 vehicles off the road every day so as to avoid the emission of 52,000 tons of CO2 every year.
