It has been long fight for the northern suburbs but, now as rumours are rife that traffic lights could be installed at opposite ends of Gobba bridge, residents are pushing to prove that a supermarket could assist in more ways than one.

Estella Progress Association president Mark Brown the current congestion on Gobba bridge - while largely due to the upgrade of the Eunony Bridge - showed a very good indication of what to expect in the years to come as Wagga set its sights on a population boom.

Mr Brown said the residents of the northern suburbs were "frustrated" that an area forecast to see the most growth is still waiting for services, including a supermarket, petrol station and effective measures for traffic flow, which appear to be nowhere in sight.

"We hope that the building and establishment of the private and public primary schools ... gives us further justification for infrastructure to be developed and constructed in the northern suburbs," he said.

"It needs to be a flow on effect to these schools being developed."

Wagga property valuer Chris Egan said traffic jams on Gobba Bridge were becoming a common occurrence, which the proposed shopping centre at the corner of Rainbow and Avocet drive could help alleviate.

Mr Egan said there is "strong backlash" from residents who want supermarkets, chemists and specialty stores in the suburb, but were instead forced to drive into the city to access.

Although it was interesting that despite the lack of action, the take up of land in the northern growth area was not affected, he said.

"If people can shop in the suburb and not have to drive into Central Wagga to shop it is definitely a benefit for the residents in the suburb," he said.

"There is a strong demand for supermarkets to go out there. On a feasibility basis, it should all work."

The status of the proposed development in Wagga's northern suburbs has been at the mercy of the banks, according to the site manager Raine and Horne.

Director Craig Tait said the developer continues to search for finance, but the banks have not been forthcoming as of yet.

"They had finances approved, but the Royal Commission [into Misconduct in the Banking, Superannuation and Financial Services Industry] changed the structure of spending and banks have tightened up a fair bit," he said.

"Before COVID-19, we were looking very positive but it has changed the risk rating for retail which makes things difficult ... so it's a contributing factor."
