The first campaign to be booked on to the tower, which shows two Mega 6 portraits, is Gatwick Airport with its 'Airport shopping just got better' tag line printed by SMP Group.
The unit is expected to achieve 1.6m impacts each day and the campaign will be complemented by a range of other outdoor activity, including train card panels.
The A3 Tower features ‘halo’ lighting to frame the advert and the campaign creative is lit by energy efficient ‘Luminaire’ LED technology, developed by Clear Channel.
A Clear Channel spokesperson said: "Our new tower at Shannon’s Corner is an iconic addition to our Pinnacle Collection and demonstrates our commitment to developing sustainable out-of-home advertising structures that complement the landscape and offer unrivalled stand-out for advertisers."
