HS2 engineers have completed three major structures on the southern approach to Interchange station, illustrating further progress on the West Midlands section of Britain’s new railway.
The trio of viaducts - Balsall Common, Marsh Farm and River Blythe - are all within the Solihull metropolitan borough.
In the coming days, engineers working for HS2’s construction partner, Balfour Beatty VINCI, will install the final parapets on the River Blythe Viaduct – the largest of the three bridges that carry the high-speed railway through Solihull, and the closest to Interchange Station – approximately 1.5 miles away.
Marsh Farm Viaduct was the first of these neighbouring structures to reach completion in summer 2025. The main structure of Balsall Common Viaduct was finished earlier this year, and all 304 parapets will be installed by spring 2027.
