We are back with Wright Archer, division engineer with the North Carolina Department of Transportation, to continue our deep dive into how roads really come together. In his first episode, Wright walked through planning and design. This time, he takes us through the next stages: how projects are bid, how construction actually happens in the field, and what it takes to maintain roads and bridges so they stay safe for decades. From traditional bid build contracts to design build and construction manager at risk models, Wright explains how NCDOT chooses the right approach for each job, how risks are shared, and why collaboration between designers, contractors, and the department can save both time and money. Then he shifts to the field, describing what happens once the plans are done: clearing and grubbing, earthwork, bridge construction, pavement design for heavy truck loads, traffic control, and inspections. Wright also digs into long term maintenance, from sealing cracks and repainting beams to managing rutting, deer strikes, cable median barriers, stranded motorists, and even the emerging challenge of electric vehicle fires. Throughout, he connects every step back to one theme: keeping people and freight moving safely.
Wright discusses:
-How different project delivery methods work in practice, including traditional bid build, design build, and construction manager at risk, and why NCDOT uses each one depending on complexity, risk, and schedule.
-The step by step process of building a road, starting with work zone setup and clearing, then moving into earthwork, structure foundations and girders, subgrade preparation, and pavement layers designed for heavy truck traffic.
-How traffic is managed during construction, including phasing, detours, lane closures, traffic control plans, and constant coordination between inspectors and contractors to keep work zones safe and projects on schedule.
-The importance of maintenance, from bridge joint and bearing repairs to pavement overlays, diamond grinding, wildlife crossings, cable median barriers, retroreflective markings, and incident response trucks that help stranded motorists and prevent secondary crashes.
With practical examples and stories from the field, Wright shows that a finished highway is only the midpoint of the journey, and that careful bidding, disciplined construction, and ongoing maintenance all play a critical role in road safety. What’s next?
