This paper presents an overview of engineering structures for the Nîmes-Montpellier Bypass (also called CNM, French acronym of Contournement Nîmes-Montpellier), which involves the design, execution and maintenance of the first dual-track, mixed high-speed passenger and freight rail corridor in France. With a total length of 80km, including 20km of connections to existing lines, this bypass includes 183 engineering structures: 12 viaducts, 1 cut-and-cover tunnel and 170 standard engineering structures. Overall, 4 years were necessary to build the CNM HSL, including 2.5 years for civil works and a total of 320,000m³ of concrete, 55,000T of steel reinforcements and 15,250T of steel frames were used. The line was opened at the end of 2017 and the maintenance is guaranteed until 2037 by the public–private partnership contract. |
