Blackfriars Station is another unique bridge along the Thames. It is a bridge…and it’s a station for the underground. When I was there in May 2012, it was under construction, or rather extensive renovation to extend the platforms along the bridge and add solar panels above. The Guardian heralded it as the “world’s largest solar power bridge” when it opened in 2014. And over a decade later, it seems to retain hold of that title, suggesting an opportunity for more solar bridges to step up to the challenge.
