Grafton bridge concrete crumbling
Crumbling concrete on 117-yearold Grafton Bridge is being investigated by Auckland Council.
Inner city residents are concerned the historic bridge, built in 1910, is being neglected by Auckland Transport with concrete sections of the bridge crumbling and glass barriers coated in graffiti and grime.
Jacqui Wilkinson, chair of the Grafton Residents Association said the bridge was ‘‘in a state of despair’’ with a chunk of concrete missing from the railing, revealing steel reinforcing.
‘‘I was wondering if somebody had been a long and smashed it,’’ she said.
Auckland Transport (AT) spokesman Mark Hannan said the missing pieces of concrete was caused by concrete ‘‘spalling’’ which occurred when water penetrates concrete causing the internal reinforcing to expand, cracking the concrete.
He said it was common in old structures and AT, which is owned by Auckland Council, monitored infrastructure like the bridge for safety.
An investigation into the concrete spalling was underway and concrete samples had been sent to a lab for testing.
‘‘There are no safety risks associated with this and there are no structural issues with the bridge,’’ Hannan said.
Hannan said following the results of the lab tests, AT would conduct necessary repairs.
It’s not just the deteriorating concrete raising concern but safety barriers covered in graffiti and filth making it impossible to see down into the gully below.
‘‘It should be cleaned once a month in regards to the motorway spill over from down below,’’ Wilkinson said.
‘‘It’s not just gross for cyclists, pedestrians and bus users but also tourists as it’s a main tourist route.’’
Wilkinson would like someone appointed as a guardian for the bridge.
‘‘Given it’s historical significance and the connection between the east and the west suburbs, somebody should be appointed for it’s heritage,’’ she said.
Mike Lee, the councillor for the Waitemata and Gulf ward echoed Wilkinsons concerns.
