Today (24/5/22) marks 50 years since the opening of the iconic Spaghetti Junction (Gravelly Hill interchange). It covers 30 acres (12 ha), serves 18 routes and includes 4 km (2.5 mi) of slip roads, but only 1 km (0.6 mi) of the M6 itself. Across five different levels, it has 559 concrete columns, reaching up to 24.4 m (80 ft). The engineers had to elevate 21.7 km (13.5 mi) of motorway to accommodate two railway lines, three canals and two rivers.
A world of wildlife and art lies below this iconic concrete structure https://www.bbc.co.uk/news/uk-england-birmingham-61482844
Heinz have even created a limited edition of Spaghetti Junction to mark this 50th anniversary!
