Wallsend Flood Works for 2021

City continues commitment to mitigating Wallsend flooding.

Newcastle council has called tenders for installation of a channel bypass adjacent to the existing bridge and demolition of a vacant building next to Nelson Street bridge.

Widening the Hunter Water channel and replacing the Tyrrell Street, Nelson Street and Boscawen Street bridges are in the Ironbark Creek Flood Mitigation Plan.

The demolition will allow the stormwater channel to be widened and avoid flooding that has occurred on a number of occasions since the Pasha Bulker storm in 2007.

Demolishing this building which we strategically acquired in 2018 is part of our more than $20 million commitment to address flooding in Wallsend,” Cr Nelmes said.

The building is directly adjacent to the stormwater channel and the Nelson Street bridge, and its removal will enable future construction of an upgraded Nelson Street bridge, as well as future widening of Hunter Water’s channel to 21 metres, which takes in approximately half the width of the building’s footprint.

Additional to increasing the flow of stormwater, the upgrade will improve the amenity of this section of channel leading into Wallsend Park, with the upgraded creek to be widened, realigned and flanked by sandstone to renew the existing concrete walled channel.

The planned improvements at Cowper Street follow a call for tender in February for the demolition of a vacant building adjacent to the Nelson Street bridge, acquired by the City in 2018 to facilitate the future widening of the Hunter Water Corporation owned Ironbark Creek stormwater channel.

Widening the Hunter Water channel and replacing the Tyrrell Street, Nelson Street and Boscawen Street bridges are key elements of the Ironbark Creek Flood Mitigation Plan.

Newcastle Lord Mayor Nuatali Nelmes said these projects are important priorities for the Wallsend community.

We are committed to delivering both the Ironbark Creek Flood Mitigation Plan and our program of traffic improvements and amenity upgrades to the Wallsend town centre, which will support businesses and residents.”

By upgrading this section of underground storm water system with larger drains, we hope to see a reduction in damaging flash flooding in the centre of Wallsend.”

The upgrade of the Cowper Street Bridge culvert is necessary before  upgrades to the nearby intersection of Cowper and Kokera Street, replacing the roundabout with traffic signals.

Further traffic improvements in Wallsend are planned under the Wallsend Local Centres Program, with upgrade of existing traffic signals at the intersection of Cowper Street and Nelson Street later in 2021 with blackspot funding from Transport for NSW.

A new Tyrrell Street Bridge was opened in April last year with $3.3 million replacement of the original 1930’s structure.

Replacement and raising of the Nelson and Boscawen Street bridges is also scheduledfor later in 2021.
