BG&E was engaged by Cardinia Shire Council to undertake a feasibility study of the proposed Lang Lang Bypass.

The purpose of the proposed bypass is to divert heavy vehicles, consisting mainly of sand and quarry trucks, away from the town centre. Diverting heavy vehicles away from the town centre promotes a safer road environment, reducing the number of conflicts with heavy vehicles and increasing amenity for residents.

The study investigated the feasibility of the proposed bypass, including aspects such as

• Traffic implications.
• Concept design considerations.
• Land acquisition requirements.
• Flood modelling.
• Environmental considerations.
• Cultural heritage considerations.
• Cost estimates.

BG&E delivered the following key scope items

• Reviewed the existing information provided by Cardinia Shire Council.
• Development of several options:
  • Preferred option (with no land acquisition) for interim and ultimate solutions.
  • Alternative option (expensive option without compromise on design standards) for interim and ultimate solutions.
• Undertook concept design development of intersections at various locations.
• Undertook and investigated flood modelling.
• Prepared a preliminary breakdown cost plan.

The project involved conducting a feasibility study and providing concept design services aimed at alleviating traffic congestion around Lang Lang town.

Throughout the project, BG&E maintained close collaboration with key stakeholders, including the Cardinia Shire Council, transportation agencies, and community representatives, integrating their feedback and addressing concerns. We carefully assessed existing site conditions and constraints such as topography, land use patterns, and environmental factors to develop a design that minimises disruption and maximises efficiency.

BG&E remained flexible to accommodate design changes and updates at various stages of the project, while also considering constructability factors to facilitate smooth implementation. We prioritised safety in design by incorporating various measures to ensure the Lang Lang bypass provides a safe and reliable transportation solution.

The project started in October 2023 and was completed in mid 2024.
