A Wagga ratepayers group has urged road users and residents along the Olympic Highway to send a message to the state government on the need for major new infrastructure.
Members of the public have until Friday at 5pm give their feedback to Roads and Maritime Services on intersection upgrades along the highway north of central Wagga at Old Narrandera Road and Travers Street.
Rural Ratepayers' Association president Barbara Johnston has called on supporters of a Gobbagombalin Bridge duplication and a highway bypass for central Wagga to use the feedback process to highlight those projects.
"To me, it won't be more than a year or so until we need a second bridge, given the growth out there," she said.
"I have been out there when there has been slow traffic or a breakdown and things just stop and people weave through North Wagga.
"All the other bridges and roads to get around it are prone to floods. They need to take all this into consideration."
Mrs Johnston said the ratepayers' association had also been campaigning for years for a bypass to "get the trucks out of Wagga".
There have been renewed calls for a bypass after a head-on collision with a truck claimed the life of a 30-year-old father-of-two on the Sturt Highway at Forest Hill earlier this month.
RMS South West NSW has previously stated that it was looking at the intersection upgrades because traffic from developments north of Wagga was "placing increasing pressure on the intersections...either side of the bridge".
"While Gobbagombalin Bridge is not being considered as part of this work, the proposed intersection upgrades will improve safety, access and traffic efficiency," the RMS stated.
Committee 4 Wagga chief executive Alan Johnston the RMS appeared to have specific goals and a limited cope for the Olympic Highway upgrades.
"They are looking to deliver on specific election promises, but I'm not going to tell people not to put their ideas in, but it in this forum or others" he said.
"Good ideas are not the sole privilege of any organisation and anybody could come up with something that could be a game-changer."
The state government committed $30 million to the highway and other roads during last year's byelection.
