The Hill car park in Bromley closed immediately on October 4 following deteriorating conditions found in a survey.
Propping work has been ongoing in recent days to improve the structural support of the car park.
The surrounding area of the car park includes key attractions such as The Glades, Churchill Theatre and Bromley Park.
Councillor Nicholas Bennett JP, Executive Councillor for Transport, Highways and Road Safety JP said at a recent meeting: “It is positive news that the car park will reopen early next week.
“This will in time for the last few days of Christmas shopping. I thank retailers and motorists for their patience while we made the car park safe.”
It has not yet been confirmed which exact day the car park will reopen.
Bromley Council explained that the concrete causing concerns in the building was not RAAC, but they were aware for more than a decade that the car park was approaching the end of its lifespan, which is why the condition has been closely monitored.
The multi-storey facility, which has been in long-term decline, had previously seen partial closure for similar concerns.
The car park on Beckenham Lane was partially demolished in 2012 in order to prolong the life span of the building.
The council says that regular condition surveys have been undertaken but latest enquiry shows that one of the concrete slabs has weakened significantly, leading to closure.
A further investigation into the car park’s condition was carried out following this and repair work began.
The car park’s regular users and season ticket holders are being advised to use nearby alternatives such as Station Road car park, the Civic Centre multistorey at Stockwell Close and several on-street parking spots until the car park reopens.
