Gatton - Helidon Road, Lockyer Creek bridge, strengthen bridge

Strengthening and rehabilitation works are now complete at the Lockyer Creek Bridge on Gatton-Helidon Road.

The Lockyer Creek Bridge is an important piece of infrastructure for freight and agriculture in the region. 

The bridge was originally built in 1966 and, after 55 years, was due for a service. It has been repainted and various parts repaired or replaced. Strengthening involved installing an external tensioning system to the bridge’s headstocks and girders. 

These works have increased the structural capacity of Lockyer Creek Bridge to maintain its suitability for type 1 road trains and ensure freight efficiency on Gatton-Helidon Road. Reducing the need for ongoing maintenance will also reduce disruptions to traffic and improve freight efficiency.


  • Improves safety

Project update

During pre-construction we discovered 4 species of micro-bat roosting in and under Lockyer Creek Bridge including:

  • the Eastern free-tailed bat (Ozimops ridei)
  • Eastern broad nose bat (Scotorepens orion)
  • large footed myotis (Myotis macropus)
  • the Eastern cave bat (Vespadelus troughtoni).

The large-footed myotis especially love living under bridges since it is so close to where they like to eat. They are a unique bat in Australian because they use their big feet to trawl the surface of the water for aquatic insects and even small fish.

Using the pier expansion joints, 2 species use this as their homes, while the others use old mud bottle nests built on the underside of the bridge by fairy martins (Petrochelidon ariel). Before construction, the nests and bats were carefully removed or relocated. Now that construction is complete, we have installed 10 bat boxes to encourage the bats to roost under the bridge again.
