Contractor appointed to repair the O’Shannassy Aqueduct Dee Slip Bridge

Repairs to the Dee Slip Bridge in the Yarra Ranges National Park are about to start with Ace Infrastructure recently appointed as the contractor.

The works will restore pedestrian, cyclist and emergency vehicle access along the much-loved O’Shannassy Aqueduct Trail on Wurundjeri Country.

The repairs will keep to the original design of the bridge. They will preserve the bridge’s heritage values by retaining as much of the existing timber as possible.

Construction timelines and next steps 

Construction starts on 24 November.

The repaired bridge will reopen to the public in late March 2026.

Access along the O’Shannassy Aqueduct Trail 

Due to the construction activity, we are restricting access along the O’Shannassy Aqueduct trail between Dee Road to the west in Millgrove and Sussex Street to the east in Warburton between 24 November and late March 2026. 

The trail will be closed between Dee Road and Sussex Street from 24 November to begin repairing the Dee Slip Bridge. 

Between 20 December and 11 January, we will reopen across along the O’Shannassy Aqueduct Trail with access around the bridge via the existing bypass track.

From 12 January until late March we will close the trail again between Dee Road and Sussex Street to finish repairing the bridge.

Access remains for emergency services throughout the construction period.
