Roadway Design

Roadway design, from freeways to neighborhood streets, requires a sense of balance.  It requires creative design approaches that optimize transportation efficiency, environmental compatibility, and sensitivity to public policies and community values within the framework of limited budgets.  It requires planning designs to accommodate vehicles as well as pedestrians and bicyclists; estimating costs accurately; and developing thorough and understandable plans and specifications.  At SEPI, we do each of these tasks everyday.  And we do it within budget and on schedule. 

Specialties include:

  • Conceptual Design
  • Interchange Design
  • Bridge Replacement Design
  • Context Sensitive Design
  • Designs ranging from local roads to complex freeways
  • Grade separated and at-grade intersection design
