The project involved removing the existing towpath surface and laying a mixture of recycled shredded tyres and gravel, bound with a clear resin, to create a smooth towpath surface for the thousands of people that visit the canal each year.
The work totalled £300,000 and was jointly funded by the Trust, Northamptonshire County Council and the Borough Council.
James Clifton, enterprise manager for the Canal & River Trust, said: “This is the last stretch of canal towpath to be resurfaced in the Borough and I'm really pleased with how good it looks. I hope local people notice the difference when they're enjoying a nice stroll or bike ride. Using recycled tyres has also meant we're doing our bit to protect our local environment and reduce the amount of waste being sent to landfill.”
