Road upgrade brings many benefits
This road upgrade involved widening the existing carriageway to four lanes and providing both on and off road cycle ways and footpaths for an 0.8km length of road in regional NSW.
The upgrade aimed to increase traffic capacity and road efficiency, improve road user safety, provide a facility for cyclists and pedestrians, develop a design that was sympathetic with the surrounding area and minimise the impact on the natural and built environment through good urban design solutions and landscaping treatments of the existing road.
RTA Central Coast office and Opus worked closely on concept development and detailed design of the upgrading of the link between the recently reconstructed intersection with The Entrance Road to the north and the existing roundabout to the south.
Our scope included the engagement of sub-consultants for a number of services including urban design and landscaping, noise assessment and other Review of Environmental Factors (REF) matters. The two main options considered during the concept development stage were to widen both sides of the road or to widen the eastern side only.
The first option affected some native trees on the west side and the second impacted on some community trees as well as a number of native trees. A comparison of the impact and other issues was undertaken prior to finalisation of the concept. Completion of concept design and the Opus team’s components of the REF process enabled the detailed design of all elements of the works to proceed towards full documentation for tender and construction.
