A giant white horse by Mark Wallinger has been picked to overlook the A2 road at Swanscombe, Kent. Organisers hope the £2m Ebbsfleet Landmark Project will be finished by 2012.
Among Wallinger's best known works is Ecce Homo (1999), which was the first sculpture to occupy the empty plinth in London's Trafalgar Square.
He won the Turner Prize in 2007. His winning work included Sleeper (2004-05), a film of a performance in which, he dressed in a bear suit and wandered aimlessly around an art gallery in Berlin for 10 nights.
Wallinger's Turner Prize-winning work also included State Britain, which recreated peace campaigner Brian Haw's protest outside the Houses of Parliament.
Folk Stones - featuring 19,240 numbered beach pebbles to represent an Allied fatality on the first day of the Battle of the Somme in 1916 - was installed in Folkestone last year.
