BBVS, the joint venture (JV) comprising SYSTRA, Balfour Beatty Group Ltd, VINCI Construction UK Ltd, and VINCI Construction Grands Projets SAS has reached two major milestones on the High Speed 2 (HS2) project in the UK.

The construction of HS2's Old Oak Common station in West London has reached a new milestone with the completion of the excavation for the massive underground box structure. This process took three years, beginning with the construction of the box's walls in June 2021. Now that the excavation is fully complete, the team will proceed to pour the final sections of the base slab to finish the box. The underground box will house six 450-meter platforms for HS2 services, while above ground, eight additional platforms are being built to serve the Elizabeth Line, Great Western Mainline, and Heathrow Express.

The Curzon 2 viaduct, also known as the "Bellingham Bridge," has reached a key milestone with the completion of four massive piers for its 150-meter-long superstructure. Designed by the BBVS design joint venture with Mott MacDonald and Weston Williamson + Partners, this sequence of viaducts will carry high-speed trains in and out of Curzon Street Station in Birmingham. The bridge will span over the existing Victorian brick rail viaduct, featuring a 25-meter-high curved truss. Additionally, it will include a unique light installation by British artist Liz West, titled Out of the Blue, which will illuminate the steel truss apertures with a vibrant color palette, creating a striking visual feature in Birmingham's urban landscape.
