Missing links – Davis Street tunnelling works
What are we doing in this area?
The upgrades in the area from Waratah Mills light rail station to Johnson Park include:
- A new tunnel under Davis Street, Dulwich Hill
- A boardwalk from the Davis Street tunnel to Johnson Park along the light rail corridor
- Installation of new solar smart path lights
- Public art in tunnel
- Wayfinding signage
- Upgrade of drainage at Terry Road
The construction method for the new pedestrian and cycling tunnel under Davis Street is a ‘top-down’ construction method, that requires specialised equipment and includes about 85 piles. The piling is complete, the concrete has been poured for the tunnel roof, the waterproofing is installed, the asphalt has been put in place, the line marking completed, and the bridge re-opened on 17 October, approximately six months after closure. The tunnel is excavated from underneath. This is the fastest method to build the tunnel and ensured the shortest closure of Davis Street bridge.
When are we doing this?
Construction of the upgrade from Waratah Mills light rail station to Johnson Park has started in April 2024 and is anticipated to be completed in 2025.
Davis Street bridge has re-opened
Davis Street bridge in Dulwich Hill is open again, after just over 6 months of closure for tunnelling works for a new GreenWay shared path connection.
