Blackpool Council is set to borrow £1.8m to cover the cost of urgent repairs to the Tower.
A £6m project to upgrade the steelwork is nearing an end, but additional maintenance needs to be done.
Coun Gillian Campbell, deputy leader of the council, said: “Our acquisition of the Tower was all about making sure it is looked after for many years to come and this work will make sure that continues to be the case.
“We are making sure that any work to the Tower is completed correctly and to the highest standard. As such, we’ve done some extra work to strengthen more of the steel which will make sure that the Tower continues to be a vital part of Blackpool’s tourism offer.
“That work has cost extra money but it is the right thing to do in order to make sure that the structure stays in the best condition. While that extra funding is significant, I want to remind people that it is a relatively small percentage of the total project.
“I also want to be clear that this money will be recouped from the income of our leisure assets and will not be a long-term cost burden on tax payers.”
