A $100 million upgrade to Redfern station will include a new concourse, new and upgraded station entrances at Marian and Little Eveleigh streets and long-awaited lift access to all above-ground platforms.

The new six-metre-wide concourse will link Marian and Little Eveleigh streets and provide new lift and stair access to platforms one to 10, final plans reveal.

The upgrade will also include changes to Little Eveleigh Street, including the relocation of on-street parking, reduced traffic through vehicle restrictions and the separation of pedestrians and cyclists through a paved cycleway.

Street parking on Little Eveleigh Street could be relocated to government land at the end of the street, with no net loss of parking spaces, Transport for NSW said.
