Rennes metro, Line B, France

The challenging construction of a tunnel in an urban setting for Line B of the Rennes metro

As part of the construction of the second metro line in Rennes, one of the largest public works projects for a regional authority in France, the Elaine tunnel boring machine built an 8-km tunnel with a 9.1-metre diameter.

The project includes construction of nine stations and five shafts that will interact with the existing line in a dense and varied urban setting and a complex geotechnical environment.
