The Balgreen Tunnel carries the tram and train tracks across a road in West Edinburgh. More than 200 people have contributed over £5000 towards the project, which has involved professional street artists and ideas and inspiration from children at nearby Balgreen Primary School.
The arched surface is now covered with dozens of giant colourful spray painted flora and fauna including otters, ducks, foxes, herons, hedgehogs, frogs, rabbits, badgers, birds, bees, beetles and butterflies.
All of the plants and creatures can be found in Saughton Park and the Water of Leith, which runs through it.
