The project involved widening an 800-metre section of the Central Coast Highway at Erina Heights from one to two travel lanes in each direction with additional lanes for cyclists, buses and parking. It included:
The challenges were:
Traffic management included design and construction of temporary arrangements while construction continued. Particularly, this allowed all traffic movements to continue while the finished surface level at Matcham Road intersection was lowered by two metres and the roundabout at Serpentine Road was removed to be replaced by traffic signals.
Our involvement with utilities included installation, removal and relocation.
The project operated under a licence from DECCW, with the following requirements:
We undertook stringent inspection and maintenance of erosion & sediment controls with daily inspections by our own staff and fortnightly inspections by the client's Environment Officers and soil conservationists.
