Bright patterned panels envelop this south London railway bridge, which designer Yinka Ilori has revived as part of this year's London Festival of Architecture.
Named Happy Street, the permanent installation is located on Thessaly Road ? a key route between Wandsworth Road and Nine Elms Lane that was previously a "forbidding environment".

The installation, which forms part of the local council's ongoing initiative to make the area more welcoming, was developed by Ilori in collaboration with input from the local people and primary school.
Happy Street, Illori's first installation in a public realm, comprises 56 patterned-enamel panels decorated with 16 different colours, chosen for their low-cost and durability.

"I am really honoured and blessed to have my first public realm project installed in Nine Elms, Battersea," said Ilori. "The most important part of the project was talking to the community, especially the young children and seeing the smiles on their faces when they walk under the bridge has been magical."
"I just hope this bridge continues to bring happiness to everyone who walks under Happy Street and inspires the next generation of young artists because they are the future," he added.

His use of bright colours across the installation is intended to echo the Thames sunsets, in a bid to encourage passersby to encourage them to become more aware of their surroundings.
