Glebe Railway Viaduct, Railway viaduct in Glebe, New South Wales, Australia.

The Glebe Railway Viaduct is a massive red brick structure with multiple large arches that spans across Wentworth Park and Johnstons Creek for more than 400 meters. Today it supports a modern light rail system and connects several Sydney suburbs to each other.

The viaduct was built in stages between 1892 and 1922 and initially carried freight trains between Rozelle and the harbor. In 1996 it was converted to support light rail, which still uses it today.

The viaducts cross parkland created on land resumed from swamps and sandflats, so the brick arches now frame Jubilee Park and Wentworth Park. Some arches of the Jubilee Park viaduct have been closed in and let as rentable space. The line carries the Inner West Light Rail, converted from the goods line in 1996.

The best way to see the viaduct is from below in parks like Wentworth Park, where you can see the brick arches clearly from ground level. You can also view it from the light rail itself if you ride the system it supports today.

The Jubilee Park viaduct alone holds more than two million bricks from the former State Brickworks at Homebush Bay, laid in English bond with soldier courses framing each arch. Its 28 spans of 10.06 metres make it the longest brick arch viaduct on the NSW rail system, at roughly 446.5 metres.
