Built for the Complexity of Modern Transportation
Confidence in an infrastructure and highway construction contractor starts with accountability and experience. For more than a century, Zachry has taken on complex transportation projects where active operations, tight work zones and intricate construction sequencing require coordination and disciplined execution. Our strength is in managing that complexity in the field. Experienced teams, extensive self-perform capabilities, specialized equipment and disciplined project controls allow us to coordinate structures, earthwork, utilities, paving and other critical scopes around the demands of each project. From signature bridges and major highway corridors to airports, ports and rail infrastructure, Zachry brings the scale and construction expertise to safely deliver transportation infrastructure communities depend on. For transportation projects requiring major utility relocations, underground electrical infrastructure or storm drainage, explore Zachry’s Underground Utilities capabilities.

Dependable Grit for the Most Demanding Highway Projects
Major bridges require a heightened level of construction planning and field execution. Zachry builds complex bridges over waterways and signature structures where deep foundations, major structural components, marine or waterway conditions and demanding construction sequences must come together precisely. Our teams understand how to coordinate the people, equipment and critical operations these landmark projects require while working around navigation, environmental constraints and surrounding transportation networks.
Zachry constructs replacement bridges, pedestrian bridges, overpasses, underpasses, retaining walls and other major transportation structures. Our precast capabilities give large transportation projects a scalable source for structural components, providing greater control over production, quality and delivery as work progresses across multiple structures. Close coordination between structural work, earthwork, roadway construction and traffic operations allows each element to advance in the sequence the larger project demands.
Highway projects demand disciplined phasing, tight coordination and work that holds up under constant use. Our heavy highway construction crews know how to manage active traffic conditions, align with project requirements and keep critical highway improvements progressing. Whether establishing a new corridor or rebuilding infrastructure within an active transportation network, Zachry delivers highway and roadway projects at scale. Our experience spans greenfield construction, existing corridor reconstruction, corridor improvements, managed lanes and concrete paving. Our long-tenured crews, self-perform resources and extensive local subcontractor and supplier network give us the flexibility to sequence work around traffic, changing field conditions and major project milestones while maintaining the safety, quality and project execution transportation owners expect.
System interchanges, urban reconstruction and major corridor programs can involve multiple structures, roadway configurations, utility conflicts and continuous traffic shifts within the same footprint. Zachry brings those moving pieces together through detailed traffic phasing, multidisciplinary coordination and field-driven construction planning, creating workable sequences that keep the project advancing while the transportation system remains in service.
Airports present a unique construction environment: Every phase must account for security, aircraft operations, passenger movement and strict operational requirements. Zachry delivers both airside infrastructure, including runways, taxiways, aprons and airfield drainage, and landside improvements such as terminal roadways, parking, utilities and site development. Across both airside and landside projects, Zachry performs the foundational civil work these facilities depend on, including earthwork, subgrade preparation and placement, lime- and cement-stabilized subgrade, underground utilities and drainage. Our experience can support private airfields and FBO facilities as well as regional, commercial, international and federal or military aviation projects, adapting construction plans to the operating environment without losing sight of critical milestones.
Zachry performs below-ballast construction, earthwork and drainage, bridges and structures, grade separations and civil improvements for port and rail yards. By coordinating civil construction around active freight, rail and port operations, our teams can advance major infrastructure improvements while respecting the access, sequencing and operational requirements that keep these facilities operational.
