The permanent installation on the newly-pedestrianised Broad Street will see four zebra-crossing-style flags painted directly on the road.
The Hockley street will be the finishing point for this year’s Pride – the annual lesbian, gay, bisexual and transgender (LGBT) celebration, which includes a parade through the city centre followed by music and speeches in Old Market Square.
The Nottingham parade takes place on Saturday, July 27.
The Labour leader of the council, Councillor David Mellen, who represents the Dales ward, said: “A rainbow road is a really visible way of showing our commitment to supporting the LGBT+ community and I’m looking forward to seeing it realised in Hockley.
“The newly-pedestrianised Broad Street provides the perfect setting. Local people have told us they want to see more street art in the area to help create a sense of place and identity – so it’s really exciting to see the rainbow road in situ to celebrate Pride.”
As well as the rainbow road, the Council House in Nottingham will be lit up in rainbow colours from Tuesday 16 July until the Pride event.
The move follows the city council’s formal motion on Monday, July 8, to reaffirm its support for the LGBT+ community.
The modern, and most common rainbow flag has six horizontal stripes, in red, orange, yellow, green, blue, and violet.
The Hockley road will be decked out on Monday, July 15, ahead of a rainbow ribbon cutting on Tuesday, July 16.
