Portsmouth's much-delayed Spinnaker Tower is finally set to open in October, the council has agreed.
People should be able to climb the tower from October
Tuesday's meeting was set to decide whether it should be opened next month, or whether it should wait until the tourist season in summer 2006.
City councillors decided it would cost more to mothball the tower than to open it in about three weeks, when work on the outside lift is completed.
The tower was originally planned to be completed in time for the Millennium.
But it has suffered years of problems and spiralling costs, which have left taxpayers more than £10m out of pocket.
A spokeswoman said 39 of the council's 42 councillors were present at the meeting - with 27 of them voting in favour of the October opening.
Leader of the council Councillor Gerald Vernon-Jackson, said: "Opening the tower in October, as soon as work to the external lift is complete, is the best financial option for our residents.
"Also, the people of Portsmouth will get the 'first look' from the tower's viewing platforms."
