How CDM Smith is leading the charge

All the experts, under one roof

Our teams work across water, transportation, energy, power and data to deliver program value. And because all our experts are under one roof, there’s no comparing the levels of communication and efficiency we’re able to achieve.

Living the dig-once philosophy

Nobody likes more traffic congestion, detours and delays. When it comes to upgrading your roadway infrastructure, Complete Corridors helps clients to think holistically and deliver maximum value with minimum disruption.

Safer, smarter, more resilient communities

Well-planned corridor projects revitalize neighborhoods, stimulate economic activity and bring communities together. We fully integrate stormwater management, environmental protections and the latest mobility innovations.

Putting things back better than we found them

What if digging up the roadway to replace your lead service lines became more than just scheduled maintenance? What if we could transform our infrastructure planning to ensure meaningful roadway upgrades? Jenny Humphreys and Sandy Kutzing are challenging leaders to think differently about utility coordination. Here they discuss how to streamline construction efforts for truly transformational results.

How will EVs and renewable energy shape the future of U.S. tollways?

How can we design, fund, and build integrated water, power, and data systems to future-proof U.S. infrastructure? The answer lies in complete corridors. Discover how collaboration across disciplines can drive lasting change at cdmsmith.com/completecorridors. As we move toward a greener, more sustainable future, the transportation sector is paving the way. Tollways have extensive land and infrastructure networks and they're uniquely positioned to lead this transition. By integrating renewable energy generation and EV infrastructure, tollways can reduce carbon footprints and deliver better services to travelers. Tollway planning and policy expert Jonathon Hart dives into how the sector is evolving to meet today’s challenges and tomorrow’s opportunities. Jonathon has dedicated his career to mentoring future leaders and building diverse and inclusive teams. He specializes in infrastructure finance, toll policy, and traffic and revenue modeling.
