Motorists have chosen Spaghetti Junction as the UK's best-known sight seen from a motorway.
Spaghetti Junction was opened in 1972 and cost about £10m to build
Birmingham's complex interchange, where the M6, A38 and the A5127 meet, topped a list compiled by the RAC from a survey of 1,000 UK motorists.
Second place was taken by the Severn Bridge, which carries the M48 between south Wales and South Gloucestershire.
The RAC Bescot headquarters, with its glass facade by the M6 in Walsall, West Midlands, came third.
Spaghetti Junction, which overlooks Aston Villa's football stadium, the 17th Century Jacobean mansion Aston Hall and the Star City entertainment complex, was heralded as the future of motoring when it was opened in 1972 by the then Environment Secretary, Peter Walker.

The Gravelly Hill interchange, as it is officially known, cost £10m to build and is held up by nearly 600 concrete columns.
RAC Rescue service delivery director Neil Thompson said: "It's a true celebration of British eccentricity that a concrete interchange is the most well-known motorway landmark.
"However, motorway driving can be extremely monotonous so it's no wonder that these iconic sites are so important to drivers and passengers alike for such varied reasons.
"The congestion predicted for this bank holiday weekend means that people will have plenty of extra time to enjoy them."
Other landmarks that got mentioned in the poll were Somerset's Wicker Man, Stirling Castle, the QEII Bridge on the M25, Ratcliffe-on-Soar Power Station near Nottingham, the Fort Dunlop factory in Birmingham, the Medway Viaduct on the M2 in Kent and Stott Hall Farm, which lies between two carriageways on the M62 in West Yorkshire.
RAC experts said they expected traffic queues to peak this weekend on Friday between 1500 BST and 1900 BST.
