Section 3A of Line 18 of the Grand Paris Express includes a 6.8 km long tunnel, eight ancillary structures and three stations, including Guyancourt. It is a buried structure with internal dimensions of 71.60 m
long, 23.51 m wide and 16.50 m deep. The underground structures are made of reinforced concrete and cast in place.
In infrastructure, it has the following levels:
- a ground floor,
- an intermediate level,
- a platform level,
- an under-platform level.
Access to the future station will be via two outlets opening onto a future avenue that will contribute to the dynamic urban transformation of the area. As part of the project, Guyancourt station was the launch pad for the Awa tunnel boring machine, which is digging the planned 6.8 km tunnel.
