NSW Roads and Maritime Services (now TfNSW) had proposed an upgrade of the 12.5km section of M1 Motorway between Tuggerah and Doyalson as part of NSW governments jointly funded $400 million M1 Pacific Motorway Productivity Package. This was to involve reconstruction of pavement and widening to provide three travel lanes in each direction along with interchange upgrades including extensions to vehicle deceleration and acceleration lanes to comply with current guidelines.

CCHD was engaged to provide key project personnel for the roles of Project Manager (Simon Cusack) and Lead Geometric Designer (Adam Hillard) for strategic investigation. Our involvement resulted in a major update to the project and was adopted as the RMS preferred Design. This included an innovative loop ramp and consolidation of the Warnervale and Doyalson interchanges to eliminate traffic weave movement brought about by close interchange proximity and an ultimate master-planning exercise that allowed provision for future North facing ramps at the Doyalson Link Road Interchange.
