Route Overview:

State Route 157 is an east-west route in the south of Wollongong, connecting the Illawarra and Princes Highways to the Shellharbour City Centre and State Route 151. Its importance has only increaswed in the last ten years, integrated with the increasing suburbanisation of the Albion Park, Oak Flats and Blackbutt areas, and the establishment of the Shellharbour City Centre. Widening to six lanes has been completed east of the Princes Highway while west of the highway the road still retains its rural feel, passing across the Flinders Creek floodplain. Any plans to upgrade this section have been postponed with the construction of Ashburton Drive between Jamberoo Road and the Oak Flats interchange in 2001.

At the time of SR157's introduction in 1974, the route was still only two-lane single carriageway road, except at its eastern end near the Warilla shopping centre. The original route was from Shellharbour Road via Lake Entrance Road, Tongarra Road (now renamed Pioneer Drive and the level crossing has since been closed), the Princes Highway and Tongarra Road to the Illawarra Highway at Albion Park. Improvements to the route began in the 1980s with widening to six lanes at its eastern end. A major deviation was opened to traffic in March 1988, New Lake Entrance Road, between Government Road and Pioneer Drive, however traffic was still required to negotiate the Oak Flats railway crossing. The most recent improvement came in October 2001 with the opening of the Oak Flats Interchange, an elevated roundabout above the Princes Hwy, a railway overpass and a new road between the Princes Highway and Jamberoo Road. This new road has alleviated any need for the upgrading of Tongarra Road in the short term.

A 1.5km duplex exists with National Route 1 on the Princes Highway although it is currently unsigned and I am yet to see evidence that it was ever signed. Nonetheless there is no uncertainty that the route indeed extends to Albion Park.
