The traffic bottlenecks of Bulli and Thirroul could in in line for some attention - but it could be some time away.
Transport for NSW is calling for public feedback on possible improvements to the Princes Highway at Bulli and Lawrence Hargrave Drive at Thirroul.
The investigation is part of the larger Illawarra Future Transport Plan, rather than a targeted approach to tackle the suburbs.
"These investigations will feed into the development of a Future Transport Plan for the wider Illawarra-Shoalhaven region, which is being prepared by Transport for NSW and is due for completion in the second half of 2020," a Transport for NSW spokesperson said.
Both locations are notorious for traffic snarls.
Traffic along the Princes Highway at Bulli has increased ever since the opening of the shopping complex that includes the Woolworths supermarket.
Residents in Thirroul have long expressed concern about traffic through the CBD, which government figures show worsens substantially on weekends when daytrippers from out of the area arrive.
"We are seeking feedback from road users and the community on their experience of these two locations to help us understand issues and opportunities in the area and to inform future improvements," the Transport for NSW spokesperson said.
"Comments about living in these town centres and driving through them, the road network and ideas about future transport needs and opportunities are all welcome."
The public can give feedback on traffic issues through Bulli and Thirroul until November 8 at rms.nsw.gov.au/bulliandthirroul.
Feedback can be left via an interactive map on the website.
