In 1993, the Elizabeth Street subway was extended and opened at the Southbank end. Conservation work was also carried out to the main building, with the external facade repainted, exterior feature lighting installed, and the stained glass feature windows above each entry restored. Further changes were made through the late 1990s with the opening of access from the main Swanston Street concourse to platform 1, platform resurfacing with tactile tiles, and the replacement of the remainder of the original platform access ramps (except platform 10) with escalators and elevators.
