The tunnel boring machine for the Metro railway under the harbour was named ‘Kathleen’. Few in Sydney now would know who Kathleen was, but in the early 1920s everyone knew Kathleen Muriel Butler, Confidential Secretary to John Bradfield during the building of the Sydney Harbour Bridge.

A remarkable young woman, the more so for her times, Butler played a vital role in the bridge construction both in Sydney and in London where she was sent to represent Bradfield and the NSW government in their dealings with Dorman Long and Co., the British contractors for the work.

On 20 November 2023 it was announced that a Blue Plaque would be erected to mark the contribution of Kathleen Butler to New South Wales.
