Bourke Road 12 x 8.4m bridge (Southern Downs Regional Council QLD)

Southern Downs regional bridge upgrades using InQuik to reduce project time, cost & complexity.

The InQuik system is a completely new way of building bridges and provides an incredibly robust, long-lasting structure that requires minimal to no long-term maintenance.

Southern Downs Regional Council identified the requirement to undertake the replacement of an existing single-lane timber bridge located at Bourkes Road, Elbow Valley near Killarney which crosses the Condamine River.

The existing bridge was a single span timber bridge of length 10m with a carriageway width of 3.6 metres across the bridge. The existing timber structure was in poor condition and the replacement was in part funded by a Bridge Renewal Program Round 4 grant.

The replacement bridge was required to be dual-lane.

Benefits of the Upgrade

  • The new bridge will cost less to maintain and will be resilient to flood events.
  • Road users will no longer have to stop or give way to oncoming traffic at the bridge.
  • Increased load capacity and two lanes will improve the travel efficiency and safety for everyone.

How We Helped

  • The InQuik integral replacement bridge is 12 x 8.4m and rated to SM1600 (168t) load capacity.
  • Integral design means the abutments are integrated with the deck, so they do not require bearings or tie-downs between the deck and abutments.
  • This bridge has a design life of 100 years with no structural maintenance required under normal service conditions, and is fully compliant with the Australian Bridge Code, AS5100 (2017).

The tender was awarded in January 2020 to local contractor Mauch Concreting.
