Cobblestones outside the Market Place shopping centre are set to be replaced with paving stones tomorrow (June 12).
There had been some problems with the tar which held the cobbles together, on Corporation Street, which had melted in the recent hot weather.
As an interim measure the council erected barriers to prevent people from getting tar stuck on their shoes and officers also cleaned the inside of the shopping centre.
In a bid to provide a long term solution that also improves the surfacing and access for all, the council has decided to replace the cobbles permanently.
The cobbles will be removed in phases by machinery, this evening (June 11). The process of laying down the flags, which will be the same as those on Market Street, will start tomorrow.
The work is expected to take several days to complete, depending on the weather.
Leader of Bolton Council Councillor Cliff Morris, said: “We know it caused a few problems for shoppers and businesses, and that’s why we’re taking action and sorting this out.
“We were looking at paving Corporation Street anyway following complaints about the cobbles from disability groups, pushchair owners and high-heeled shoe wearers.
“We’re still trying to get to the bottom of what happened with the tar and we are in discussions with the supplier about it.”
