Gravelly Hill Interchange, nicknamed ‘the Spaghetti Junction’, is the 6th junction of the M6 motorway, where it joins the A38 Aston Expressway in Birmingham, UK. The name “Spaghetti Junction” was coined by Roy Smith, a journalist from the Birmingham Evening Mail in the 1970s. The areal view of the junction sure tells us why it is called the Spaghetti Junction. Spanning an impressive 30 acres, the junction serves 18 routes and includes 4 km of slip roads. Across 6 different levels, there are 559 concrete columns, reaching up to 24.4 m in height. The engineers had to elevate 13.5 miles of the motorway to accommodate 2 railway lines, 3 canals, and 2 rivers. It’s the most complicated junction in United Kingdom.
