The NSW government will spend $745,000 on improvements to Appin Road in the first half of 2014.
The road has been an accident black spot in recent years, with a number of crashes and fatalities.
It has received a lot of attention from the government, including a safety review, speed limit review and road resurfacing and rebuilding at several locations to improve safety and traffic flow.
The government has earmarked $745,000 to be spent on rehabilitation work on the road before the end of the financial year.
The funds are part of the $46 million the NSW allocated to maintain roads in the Illawarra in the 2013-14 financial year.
Roads Minister Duncan Gay said the figure represented an 11 per cent increase on the $41.3 million the previous government spent on the region's roads in 2010-11.
However that 11 per cent figure was the lowest increase of seven key regions in NSW, and the second lowest allocation overall. Only the Central Coast, with $36 million, received less funds.
A spokesman for Mr Gay said the $46 million covered pothole repair, road resurfacing, tidying vegetation and removing graffiti.
Most of this work was done on an as-required basis as soon as problems were reported.
However, he said there was also work planned in advance, such as that on Appin Road.
Lawrence Hargrave Drive would also be allocated resources in the first half of 2014, with at least $1.8 million spent, including rehabilitation work at Stanwell Tops, and replacement of culverts at Helensburgh and Scarborough.
Rehabilitation work would also be carried out on the M1 Princes Motorway at Berkeley ($880,000) and Figtree ($500,000).
Resurfacing work worth $255,000 had already been completed on three M1 ramps at Figtree and West Wollongong.
Resurfacing the Princes Highway at Kiama and the Illawarra Highway at Albion Park cost $274,000 and $124,000 respectively.
Just over $500,000 was spent in the second half of last year on the northbound lanes of the Princes Motorway near Bellambi.
Also, $1.3 million was spent on rehabilitating the Princes Motorway at Maddens Plains.
