At Trihydro, we deliver comprehensive roadway design and engineering solutions that span the full project lifecycle—from initial planning and design through construction management and post-construction support. Our multidisciplinary team integrates expertise in roadway design, right-of-way acquisition, utility coordination, drainage engineering, environmental compliance, and multimodal transportation planning. We are committed to creating safe, accessible, and resilient transportation systems that meet the needs of all users. Our designs strictly adhere to AASHTO, DOT, and ADA standards for regulatory compliance and long-term performance. Through detailed site evaluations and stakeholder collaboration, we deliver cost-effective, high-quality solutions that enhance mobility, safety, and community connectivity.
Trihydro provides services for street and roadway projects, beginning with preliminary reconnaissance and extending through final construction administration. Our capabilities include:
We also support land acquisition processes by preparing legal descriptions, managing appraisals and negotiations, and verifying compliance with local and federal requirements. Our integrated approach enables each project to be delivered on time, within budget, and aligned with community goals.
Recognizing the importance of active transportation, Trihydro designs pedestrian and cyclist infrastructure that promotes safety, accessibility, and connectivity. Our services include:
We go beyond regulatory compliance to create inviting, user-friendly environments that encourage walking and biking. Our designs consider comfort, aesthetics, and integration with the surrounding built environment, supporting healthier and more sustainable communities.
Intersections are critical nodes in transportation networks, and Trihydro approaches their design with a focus on safety, efficiency, and context sensitivity. Our process includes:
By applying advanced modeling tools, we develop intersection solutions that reduce conflict points, improve traffic flow, and enhance multimodal access. Our designs are tailored to the unique needs of each location and consider long-term functionality and community benefit.
OUR FEATURED PROJECTS
Over the years, we’ve helped clients navigate everything from assessment and remediation to permitting and monitoring, and from mine land reclamation to wildfire risk mitigation, and beyond. What sets us apart is our dedication to understanding the specifics of each project—and strategically applying our technical expertise. Our work is guided by a simple principle: leave it better than you found it.
