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.
