Interchanges

Redditch is home to something extraordinary. Something big, and absurd, and noticed by almost nobody. Redditch has a cloverleaf interchange.

Back in 1972, one Birmingham newspaper found Spaghetti Junction so devilishly complex that it published a pull-out-and-keep guide to navigating it.

Free-flowing, resizeable and also quite pretty.

A cheap and cheerful way to fully grade separate two intersecting roads.

A clever improvement on the cloverleaf.

It is big, and it is clever.

Four symmetrical loops — it's impossible to miss a cloverleaf. If you can find one, that is.

The simplest free-flowing three-way connector.

Three levels of road, three roads connected, three ways to build it.

The true British interchange.

A junction with no bridges and not much choice if you're on the side road.

Halfway between a diamond and a roundabout interchange.

A conventional, basic motorway-to-road connection.

It might be the simplest type of interchange there is. One way on and one way off: a fork in the road.

Officially the seventh most frightening thing on the road network - but actually it might just be the most efficient junction ever designed.
