A City of Sydney councillor is leading a push to resurrect a rainbow crossing at Taylor Square.

In 2013, a rainbow crossing was painted across Oxford Street at Taylor Square in Darlinghurst by the council in the lead up to Mardi Gras.

It became a tourist attraction and a social media hit.

But Roads Minister Duncan Gay controversially ordered workers to cover it up with a layer of fresh asphalt, arguing it was dangerous because people were stopping in the middle of the crossing to pose for photos.

Now, City of Sydney councillor Christine Forster has written to Mr Gay, proposing a new rainbow crossing be painted at a safer location, at the intersection of Bourke and Campbell streets on the southern edge of Taylor Square.

Taylor Square's rainbow crossing was covered in asphalt in April 2013.

"It's every bit as close to the heart of the community, the LGBTI community, in Taylor Square, but it's a much safer and quieter location where people would be able to stop and take photos and enjoy it without being in danger of being run over by a bus," Ms Forster said.

"Even if people did skylark around on it a little bit, which I suppose you can't avoid in some instances, it's a pretty safe proposition."

Ms Forster, who is openly gay and the sister of former prime minister Tony Abbott, also said the move would be especially timely given Australia may soon go to the polls in a plebiscite on same-sex marriage.

"We really want to be united and showing our support for change, for reform to the marriage act," Ms Forster said.

"It's going to be a very important time that we put positive symbols out about our community, so I think all round it's great timing."
