The interchange's colloquial name "Spaghetti Junction" was coined in
1965 by journalists from the

The junction provides access to and from the A38 (Tyburn Road), A38(M)
(Aston Expressway), the A5127 (Lichfield Road/Gravelly Hill), and
several unclassified local roads. 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 5 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
In 1958, the Ministry of Transport commissioned the engineering firm,
Sir Owen Williams & Partners, to investigate possible routes to
connect the M6, the A38(M) and the A38 trunk road.
The development of the interchange was approved and announced in
August 1968 by the then Minister of Transport, Richard Marsh.
Construction was expected to take three years and to cost £8m.
Construction started in 1968 and the junction was opened in May 1972
by the then Secretary of State for the Environment, Peter Walker.
The opening was delayed by several months because of "box girder
inspections". These followed the interim report of the Merrison
Enquiry set up following the collapse of similar box girder bridges in
Australia and Wales. In an unusual meeting of old and new transport
technology, the pillars supporting the flyovers over the Birmingham
Canal Navigations had to be carefully placed to enable a horse-drawn
canal boat to pass under the interchange without fouling the towing
rope. The junction has undergone major repair work several times
since, owing to the very heavy traffic through the junction, and some
alleged cost-saving measures during its construction. In November
2007, a sliproad running from the Tyburn Road onto the Aston
Expressway was closed to undergo urgent repair works. Upon inspection,
it was found that
