Modernizing transportation systems is vital to our mobility. 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.

More than half of Shannon & Wilson’s work is transportation-related. Our firm 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.  Shannon & Wilson projects include new design, retrofits, and safety studies for:

  • Major arterials and roadways
  • Bridges
  • Overpasses, tunnels, and viaducts
  • Railroads and Transit systems
  • Ports
  • Airports
  • Grade separations
  • Intermodal facilities
