The Carillion team behind the Morpeth Northern Bypass project is donating £1,000 to two organisations.
The company bid for funding to support the local community and it has been awarded with two separate pots.
Northumberland Wildlife Trust will receive £500. The money will be allocated to its campaign to help educate local river users on the conservation efforts for the endangered native white-clawed crayfish.
The other pot of £500 will go to Sustrans to support its work across south east Northumberland – this involves encouraging people to make journeys by bike and foot where possible.
Sustrans will use the funding to buy ‘balance bikes’, the most effective type of cycle for teaching young children how to ride.
Scott Beattie, project manager at Carillion, said: “As a business, we want to contribute to improving the local communities we work in, not just building a road.”
