Sandra Baxter drove taxis in the city for 38 years and believes the stretch of highway at Alfredtown has "always been an issue".

A Wagga couple, aged in their 70s, died on August 30 after they pulled out of the 'Shanty' service station in Alfredtown and were hit by an oncoming semi-trailer heading east on the highway.

Ms Baxter said she regularly drove Wagga residents to and from the Shanty when it was still a hotel.

"I suppose the roads have changed since then, but the highway's still the same. It's still dangerous," she said.

"They should do something out that way, they really should. It's not fair to have two lost lives."

Ms Baxter is calling for better signage warning drivers from both directions of the upcoming service station and the intersection where Alfredtown's River Road and Tumbarumba Road meet the highway.

Ms Baxter believes a dual carriageway would make it safer for vehicles travelling through Alfredtown or pulling into the service station.

"It's not so much I'm blaming the trucks ... but coming down that hill you haven't got a chance to get out of their way," she said.

"It's very important if it saves lives. It only needs to save one life to be beneficial."

A Transport for NSW spokesperson said works recently completed at the Tumbarumba Road intersection provided improved lighting, a new median and road widening to better cater for traffic turning movements into and out of the road from the Sturt Highway.

"Transport for NSW is not currently considering the construction of a third lane on the Sturt Highway, but will investigate removal of vegetation to improve sight distance for vehicles turning left out of the service station," the spokesperson said.

A Borambola resident who drives on the Sturt Highway almost every day said she recently had a frightening near miss in Alfredtown.

"A bloke goes out in front of me ... he's put his brakes up to turn into the Shanty and there's no turning lane and he's stopped in the middle of the road," she said.

"I'm trying to stop behind him going from 100 kilometres an hour."

Tarcutta's Theresa Ryan wants to see improved signage on either side of Alfredtown and more lighting at the Tumbarumba Road intersection.

"They need something to light up the road there. I've come home at night there and it's pretty dark" she said.

Transport for NSW has said it will review intersection signage and consider installing signs at the service station entrances.

The department said a speed zone review of the Sturt Highway through Alfredtown will also be carried out to assess the most appropriate speed limit.
