Bridges + Structures

We provide planning, design and construction engineering services for bridge replacements and repairs and sound and retaining walls.

Our engineers have experience in providing bridge inspection, planning, preliminary engineering design, final design, and construction support services.

We offer a full range of new bridge and bridge rehabilitation design services: from simple culvert extensions and noise and retaining walls, to bridge load analysis, deck replacement, bridge widening and new river or railroad crossings. HR Green’s services have provided for structures that complement a larger engagement such as corridor development and gateway features and standalone structures that include vehicle and pedestrian facilities.

We also perform bridge safety inspections. The work includes an update of the existing Bridge Inspection Databases and the completion of the structure information system Routine Inspection Forms, Special Feature Inspection Forms and Underwater Inspection forms. We are also responsible for a summary, describing bridges in need of repairs, the scope of repairs needed, and a budget estimate of repair costs.
