The new Rainbow crossing was installed overnight on Tuesday in Lavender Hill, close to Battersea Arts Centre.
The location has been chosen because of its high profile. It is one of the borough’s busiest crossing points and is situated next to a major local landmark.
The crossing will feature the colours of the internationally recognised Pride Flag which has come to symbolise diversity and pride of the LGBTQ+ community worldwide.
The council’s transport spokesman Cllr Paul Ellis said: “Here in Wandsworth we are hugely proud to show our support for the LGBTQ+ community.
“Our borough has a long history of supporting diversity and equality so I’m delighted to be able to announce our first rainbow crossing in Lavender Hill.
“We want all our residents and communities to know that we are here with them, we support them, and we are working hard to make sure our borough is a place where people feel safe, free from discrimination and proud to be themselves.”
David Robson, Chair of the Wandsworth LGBTQ+ Forum added: "Over the last 12 months Pride crossings have been popping up in boroughs across London as a way to celebrate Pride Month but not all are permanent.
“I'm pleased to see that Wandsworth have shown such a visible celebration of its LGBTQ+ Community by installing this as a permanent crossing at an iconic location.
“It's a brilliant way to celebrate the borough’s LGBTQ+ Community and in the absence of Pride in London 2020, it will mean a lot to people."
A formal opening ceremony will be held at the crossing next week.
