The Osborn Road car park, in Fareham town centre, was built in 1973 and now needs ‘significant investment’ in order to remain usable beyond 2022, according to Fareham Borough Council
The agreed refurbishment plans aim to improve the structural integrity of the building, as well as creating wider spaces, improved lighting and better demarcation.
Council leader Sean Woodward, said: ‘Osborn Road multi-story car park is a valuable facility for both shoppers and town centre workers, with around 430,000 cars using it a year.
‘It is however looking tired and dated now, so I’m pleased that this project has been given the go ahead.
‘Once completed, the refurbished car park will provide a much better experience for drivers and will help to encourage visitors to the town centre.’
The council plans to begin the improvements in the summer of 2021, with the aim of keeping as much of the facility open as possible throughout the works.
Last month the council introduced charges across its coast car parks, in part to raise revenue to undertake the Osborn Road.
The coastal car parks will see a charge of £1 per hour – up to a maximum of six hours – from 10am to 6pm each day.
