Highway, Cloverleaf, Transportation Construction


For decades, WSSI has been an essential partner in some of the most complex roadway, rail, transit, air, pedestrian, and multimodal transportation projects in the Mid-Atlantic region.

From highways to local sidewalks and everything in between, we work with private and public stakeholders to keep projects moving.

Mapping out the road to success

We help get projects started right – providing insight in the planning stages with environmental, natural resource, and cultural resource constraints analyses, feasibility studies, and NEPA documentation. We bring projects through permitting and regulatory approvals with federal, state, and local agencies, and see them through to compliance during construction and maintenance.

We help you get there

We routinely work with public agencies, the private sector, and Public-Private Partnerships on projects that benefit communities. We also support Departments of Transportation directly via programmatic planning and implementation, on the ground support, and facilities inspections for their internal infrastructure and management.
