The Mall is about to start phase two of a series of planned works to refurbish the entrance to the central car park.
It is costing owners Capital & Regional more than £180,000, which marks a significant investment in the shopping centre with the aim of improving the car park for shoppers.
Phase one - which encompassed the covered entrance – is complete. It will reopen on Sunday (July 21).
At the same time, work will start on phase two which includes improvements to the exit ramp.
This will close on Sunday at 7pm and will remain closed until Monday, August 19.
All vehicles entering the central car park will need to leave via the Market car park. Relevant signage will be in place.
The closure of the exit coincides with work being carried out by Luton Borough Council and the National Grid on Bute Street, which will be closed for about four weeks.
Operations Manager Roy Greening said: “By August you will see a vast improvment in these areas.”
