Princes Highway Upgrade, Gerringong

Completed: 2015

The Princes Highway upgrade at Gerringong was officially opened by the Premier for NSW, the Minister for Roads, Freight and Maritime and the Kiama MP in August 2015.

This 7.5 kilometre project is the first completed stage of the three part upgrade of the Princes Highway between Gerringong and Bomaderry, and includes two new interchanges providing access to Gerringong and Gerroa.

Located in the gently rolling landscape of the NSW South Coast, the upgrade of the Princes Highway provides highway users a rich driving experience and connection to the natural landscape and the constant interaction of ocean and beaches, rocky headlands, narrow coastal plains, escarpments and coastal ranges.

A new incrementally launched bridge at Fern Street has replaced a railway level crossing and provides a much improved connection into Gerringong. The new bridge offers road users an elevated view across the Rose Valley and Omega Flat, enhancing the sense of entry into town.

The southern town access at Belinda Street was also upgraded with a new interchange featuring refined and textured retaining walls and a highway overbridge.

The project’s integrated landscape design enhances the new distinguished town entrances, and throughout the project assists in blending the new highway formation with the gentle slopes of the local landform. At Rose Valley Road in the north of the project, impact on two iconic and locally significant fig trees and the Renfrew Park property was avoided through innovative design, with consequent improvements in local road connectivity and access.

Throughout the project the design has sensitively responded to its highly prized landscape setting including the constant presence of the Illawarra Escarpment which unites the local community, tourists and other highway users with its majestic scenery.
