The artwork, made from reclaimed oak, was jointly funded by Arts Council England and Natural England.
Mr Merrill added that the piece was inspired by “the idea of family networks and family trees growing into something that is ready to flourish”.
The 10ft (3m) tall sculpture was commissioned by Bradford-based non-profit company The Leap, which supports community-led arts and culture across the district.
Zulf Ahmed, The Leap director, said: “The installation of this artwork is the culmination of years of planning and preparation.
“We’re so pleased that in this City of Culture year, we’re able to bring something new and inspiring to the famous Leeds Road corridor – a part of Bradford that is known for its strength through its diversity.”
Paul Duncan, deputy director for Natural England in Yorkshire, said: “We hope that this beautiful new sculpture will inspire visitors and the local community to explore, celebrate, and understand their natural heritage whilst helping to tell the story of this special place for generations to come.”
