Higher load limits on $6.88 million replacement bridge in Lockyer Valley

A 15-year-old bridge that was badly damaged during 2013 floods and therefore subjected to a 42.5-tonne load limit, is set to finally be replaced.

The existing Mahon Bridge at Carpendale, in Queensland’s Lockyer Valley, will be demolished, to make way for a new two-lane concrete bridge of around 40 metres.

Though work was supposed to get underway late this year, the Lockyer Valley Regional Council says it has delayed the works to reduce the overall time the bridge and Carpendale Road are closed due to the contractor’s Christmas shutdown.

Infrastructure portfolio councillor Michael Hagan said the decision was made to decrease the level of disruption and inconvenience to road users and residents.

“The replacement of Mahon Bridge is expected to take about six months to complete, weather permitting,” he said.

“If the weather is favourable, this delay is not expected to change the completion date of the project, which is scheduled for mid-next year, as the overall project had included long lead times.”

Damage to the existing bridge means it has also been subject to a one-lane traffic arrangement.

“Significantly, the new bridge will improve the road alignment and increase the load limit and accessibility for heavy vehicles over the bridge for one of the region’s largest employers,” Hagan said.

During the demolition and construction phase, a full closure of Carpendale Road will be required.

Hagan added that residents and businesses in the vicinity of the bridge have been notified. “Council acknowledges the construction of the new bridge will cause additional noise and traffic, especially along the detour route, and we ask the community for its patience and understanding during the construction process.

“Once the new bridge is operational, the number of heavy vehicles travelling the alternative routes will be slashed, which is a major long-term benefit.”
