Integrated road and highway engineering 

CDM Smith delivers comprehensive roads and highway engineering services that support safe mobility, efficient network performance and long-term resilience. Our teams design road infrastructure that responds to traffic demand, land-use growth and regulatory requirements—balancing safety, capacity, and constructability. From urban streets and major corridors to complex interchanges and network upgrades, we integrate technical analysis with practical design to deliver solutions that perform in real-world conditions and support sustainable transportation outcomes across the full project lifecycle. 

Urban roads and highway engineering 

We design urban streets, arterial corridors and highways that respond to traffic demands, land-use development and environmental context. Our solutions balance operational efficiency, safety and constructability across diverse project scales. 

Interchanges, intersections, and roads network upgrades 

CDM Smith delivers complex interchange and intersection designs, road widening schemes and corridor upgrades. Our work is informed by detailed traffic analysis to reduce congestion and improve overall network performance. 

Road safety and multimodal integration 

We incorporate road safety audits, pedestrian and cyclist facilities, and public transport considerations into our designs—supporting safer, more inclusive transport systems for all users.

From concept design to construction support 

Our teams support the full project lifecycle—from feasibility study and preliminary design to detailed design, tender documentation and construction-supervision services—ensuring coordination, compliance and buildability.
