Outdoor market traders have temporarily relocated to the square to trade on Tuesday and Thursday.
Local firm Seddon is now working to improve the outdoor market area, add a new food hall and make other improvements to entrances and the fabric of the building.
The new-look Bolton Market will offer a wider variety of stalls, appeal to younger shoppers and create a space where people can meet and socialise in the evenings.
The ultimate aim is to increase both the number of visitors and the amount of time they spend there.
Expected to be operational for two to three weeks every Tuesday and Thursday, the new location has caused mixed opinions amongst stallholders.
Tim Davies, who’s been selling clothes for 15 years on the market, said: “I’m quite happy with it yeah, we’ll just have to wait and see how it goes.
“It’s a bit tighter on space so I haven’t got as many clothes as I would on the [original] market.
“We’re quite busy anyway, so at the moment everything seems to be going as normal.”
Fellow vendor, Jibrel Ismail spoke even more positively about the short-term change, he said: “It’s more crowded, there are more people who can come and check it out.
“We get more people than when we are on the market.”
Trading since 1986, Mister Dilal however wasn’t as positive about the switch, he said: “No, I like an open market that’s better.”
Mister Dilal also went on to state how he’ll be hoping to return his children’s clothes outlet to the Grade 2 listed building sooner rather than later.
One of the UK’s oldest food markets, the marke has been undergoing renovation work in excess of £5 million for the past year.
