Moving forward –
modernizing transportation

Aging infrastructure, funding, congestion, remote access, land development, movement of goods, safety, and protection of our natural resources all play a crucial role in transportation projects.  With more than half of our work focused on transportation-related issues, Shannon & Wilson integrates geotechnical, environmental, and natural resource services to provide a single source for multiple project challenges. We provide design and construction solutions that balance transportation needs, financial resources, and environmental considerations.

We conduct geotechnical studies and provide recommendations for foundation design, earth retention, pavement, and site drainage, and provide environmental and natural resources services to address the impacts of transportation development.
