Scaffolding is set to be installed around the outside of Mansfield's Walkden Street multi-storey car park, and the car park will remain open as usual.
Work will begin to erect the scaffolding on October 12.
The scaffolding will be put up after Mansfield District Council became concerned about the safety of external panels on the Walkden Street multi storey car park, andclosed Stockwell Gate to traffic.
It will take about four days to erect and will be in place for between three to six months until work is complete to ensure the concrete panels on the exterior of the building are safe.
Mike Robinson, director of economic growth, said: "We are advised that the car park itself is safe and will continue to operate as normal but Stockwell Gate will have to be closed to traffic during this time. It will remain open for pedestrians.
"We are taking this action on the advice of structural engineers and their concerns about some of the panels on the outside of the car park. We can only apologise for any inconvenience this action may cause but public safety is our paramount concern."
Safe access to shops underneath the scaffolding in Stockwell Gate, including B&M Bargains, Pound Stretcher and the British Heart Foundation, will be maintained.
Stockwell Gate is a small one-way largely pedestrianised street with a few parking spots for permit holders to use from Sunday to Wednesdays.
The closure will affect the road from at the junction Rosemary Street to the junction of Queen Street
