The largest piece of commissioned art in Liverpool is due to be unveiled on Monday.
The structure is 30 metres high
The Mersey Wave stands on either side of Speke Boulevard, which leads up to Liverpool John Lennon Airport.
The illuminated structure has 12 giant aluminium fins, each 30 metres high and weighing 5.4 tonnes and can be seen from up to a mile away.
The Wave was designed by Czech-born lighting artist Peter Fink and Igor Markov of Art2Architecture.
It was commissioned by Liverpool Land Development Company (LLDC), and paid for mainly by the North West Development Agency (NWDA).
The structure is to be switched on by the Lord Mayor of Liverpool, Councillor Ron Gould, LLDC chairman, Ray O' Brien, and executive director of the NWDA Helen France.
