A crucial part of Hamilton's infrastructure was given new support on Monday when contractors positioned steel pier supports underneath a sewer overbridge crossing Wairere Drive.

The eastbound lane of Wairere Dr, between River Rd and Resolution Drive, was temporarily closed as contractors lifted into place two new steel bridge pier supports.

Next Monday, the same 550-metre section of Wairere Dr will be temporarily closed as workers strengthen bridge trusses above the new piers and then jack the bridge a few centimetres to attach the new bridge supports.

Work will also include removing the existing central steel pier that supports the bridge.

The removal of the central pier is required to accommodate two extra lanes of traffic along Wairere Dr.

Council spokeswoman Natalie Palmer said the bridge work was "extremely important".

"Removing the central pier is a critical component in the project as it creates the space needed for the additional lanes," Ms Palmer said.

The pipe underneath the overbridge is the main sewer interceptor for the eastern side of Hamilton.

Ms Palmer said fine weather had helped contractors complete some of the high risk items which were dependent on ground water levels.

"We are anticipating some time savings but cannot say for sure at this stage as there are still significant challenges," she said.

Four-laning the section of Wairere Dr is expected to be completed by September and is regarded as an integral part of the $84m Hamilton Ring Road project.

Once completed it is expected to improve traffic flows in the city's northeast.
