New bridge construction on target

Construction of the new Pyramid Bridge, over the Mataura River, near Riversdale, had been going well until Mother Nature threw a curve ball last week.

The recent flooding has caused some issues for the construction crew. Until then the weather had been playing its part.

“The seasons had been kind up until last week, meaning we’ve been able to get on with the job,” says Gore District Council transport manager, Peter Standring.

Until last week’s flooding, progress on the new bridge had been going well.

Work began in November last year to replace the 1930s Pyramid Bridge which partially collapsed after flooding in February 2018. The new bridge, a widened single-lane structure, is expected to be finished by the end of March 2020, with the approach work finished by the end of June.

While the new bridge connects with the river’s western bank at the same place as the old bridge, it’s overall alignment is straighter. This means it connects slightly upstream on the river’s eastern side when compared with the original bridge.

“This realignment will improve access and the safety of approaches, particularly on the eastern side,” Peter says.

The new bridge is 20 metres shorter, as its new abutments will jut out further into the river.

There’s still more piling and earthworks to be done before the bridge is finished.

NZ Transport Agency is contributing 73% of the total construction cost of $3.79 million with Gore and Southland district councils sharing the balance.

“We’ve appreciated the community’s support and patience while this work has been underway. We know that having this bridge out of action has been an inconvenience to many who live locally and thank them for their consideration,” Peter says.
