Complex staging in live traffic demands more than a compliant design — it needs a strategy that can move seamlessly from tender through to delivery.

In our latest feature with The RoadBuilder, we share how D-TAL combined constructability, civil design and traffic management expertise to support the M7–M12 Interchange with a constructability-led temporary traffic management strategy.

This approach delivered:
• Zero redesign post tender
• TTM strategy implemented seamlessly in the field
• Value-engineered staging that improved the program and reduced cost

By bringing construction, design and traffic management expertise together from the outset, the team developed a staging strategy designed not only to work on paper, but to work in the field.

No redesign. No surprises. Just delivery.

When independence matters, confidence follows.

D-TAL is proud to have supported the Albury to Illabo section of Inland Raill by delivering an independent Road Safety Audit (RSA) for Kemp Street bridge, supporting Martinus Group in the delivery of critical bridge replacement and clearance upgrade works. 🚧

The engagement fulfilled a key project requirement by providing an independent assessment of the proposed design for Martinus Group and Transport for NSW.

As the independent auditor, D-TAL was not involved in the design process. This separation ensured an objective review focused solely on identifying road safety risks and improving outcomes for all road users throughout construction and into operation.

Our assessment considered:
• Road user safety for motorists, cyclists, pedestrians and heavy vehicles.
• Safe movement for all road users (motorists, cyclists, pedestrians) through the scope of works and adjoining local roads and intersections.
• Potential conflict points between different road users.
• Visibility, driver decision-making and road user expectations.
• Pedestrian and cyclist access, continuity and safety.
• Signage, guidance and overall road user understanding.

Independent road safety audits provide an important layer of assurance, helping project teams identify risks early, improve safety outcomes and deliver infrastructure with greater confidence.

If your project requires an independent Road Safety Audit or road safety advice, we'd be pleased to help.

Keeping traffic moving while building critical infrastructure isn’t simple—but it’s exactly what we delivered together on the Singleton Bypass – Southern Connection (Stage 2A).

D-TAL is proud to be partnered with ACCIONA and Transport for NSW to support this milestone, providing a comprehensive Temporary Traffic Management (TTM) strategy and design that kept the New England Highway operational throughout major construction works.

Working closely with Acciona, we engineered how traffic could be safely staged, diverted, and maintained at 60 km/h—all within a constrained and active corridor. This collaboration enabled:

✔️ Continuous traffic flow with minimal disruption to the community
✔️ Safe and efficient separation between live traffic and construction
✔️ Streamlined delivery of critical permanent works

Our construction maximised permanent pavement construction works behind barriers

Considered critical level difference between existing and permanent pavement levels to ensure safe traffic movements.

This project demonstrates how construction expertise and design-tested TTM strategies can unlock complex infrastructure delivery—keeping communities moving whilst maximising construction productivity.

👏 Proud to be part of the Singleton Bypass team alongside our partners ACCIONA and Transport for NSW in delivering infrastructure that keeps communities moving—both now and into the future.

At D-TAL, we don’t just manage traffic—we work with our partners to design certainty into every stage of construction to ensure project delivery.
