Youngsters from Danesholme Primary School in Corby came up with a bright idea to tackle graffiti on their estate.
About 20 pupils, aged eight to 11, grabbed rollers, brushes and paint pots and transformed the underpass in Viking Way.
Using green, yellow and blue paint they covered the graffiti and added finishing touches by planting up nearby flower beds.
Leader of Corby Council, Cllr Tom Beattie, said: “A lot of work is taking place within Corby to make the borough a cleaner and greener place, to raise awareness of environmental issues and to get residents involved in taking pride in their area.
“Over the last couple of weeks we have had campaigns which have tackled dog fouling, fly-tipping and litter and now we are focussing on graffiti.
“We were very pleased to work with pupils from Danesholme Primary School on this project which has transformed and improved the underpass for the whole community.
“Graffiti can really taint an area and we hope that the work the youngsters have put in will go some way towards deterring people from creating any further problems here in the future.”
The pupils are the schools community champions and they have already been involved in picking up litter in the area.
Headteacher Karen Rolf said: “The school is at the centre of the estate and the pupils are all enthusiastic about playing their part in the community.”
