Connected Communities are Better Communities
We partner with local councils, state road authorities, and private developers to deliver transport solutions that are safe, efficient, and built for the future.
We design the essential infrastructure that keeps communities connected—bridges, roads, and transport networks that support growing cities and industries. Our engineering expertise spans everything from bridges and intersections to major road upgrades and transport precincts, including Project Verification.
Transport projects are complex. That’s why we focus on practical, buildable designs that integrate seamlessly with existing networks. Whether it’s designing access roads for a windfarm, managing precinct-wide infrastructure, upgrading major motorways, or supporting critical road and transport around major Australian airports, we bring technical excellence and a solutions-driven mindset.
We collaborate closely with contractors, traffic engineers, and specialist disciplines like flooding and hydrology to deliver well-informed, cost-effective outcomes. Our experience in design and construct (D&C) projects ensures we create efficient solutions that work in the real world.
From local road improvements to multi-million-dollar transport corridors, we help deliver smarter, more connected infrastructure—keeping people and businesses moving.
“What I love about Northrop is the diversity of projects we get to work on and the strong relationships we build with our clients. We work closely with them to truly understand their objectives, making problem-solving a rewarding and collaborative process.”

We work across various types of delivery models, adapting our approach to meet project needs—whether it’s preliminary concept design, detailed engineering, or independent verification and peer reviews. Our experienced team focuses on flexibility to meet client project requirements.
We understand the approval pathways for major transport projects, working closely with councils, state road authorities to ensure fast, compliant, and hassle-free approvals.
From highway upgrades to new transport precincts, we’ve successfully delivered large road infrastructure projects, ensuring real-world, buildable outcomes that meet client and community needs.
We focus on practical, efficient solutions that streamline construction, reduce material costs, and minimise project risks—helping contractors and clients deliver on time and within budget.
