Bridge Design
Fixed Bridges
Our engineers design fixed bridges of all types and scales—from small rural crossings to complex multi-span structures on major highways. We utilize state-of-the-art modeling and design tools to ensure structural safety, longevity, and cost-effectiveness. Services include:
- Precast and cast-in-place concrete spans
- Steel girder and composite beam structures
- Slab span and box beam bridges
- Culvert and drainage crossing integration
- AASHTO- and LADOTD-compliant design
Movable Bridges
Huval & Associates has extensive experience in the specialized field of movable bridge design. These structures require expertise in structural, mechanical, and electrical systems to provide reliable operations under demanding conditions. Our services include:
- Bascule bridges
- Swing-span bridges
- Vertical-lift bridges
- Operator houses and control systems
- Mechanical and electrical design for drive, lift, and control components
Bridge Replacement
We design replacement structures that improve safety, increase load-carrying capacity, and minimize disruption to the traveling public. Our approach balances modern engineering standards with cost and schedule efficiency. Services include:
- Demolition planning and staging
- Design of replacement spans to current load-rating standards
- Hydraulic and geotechnical evaluations for foundations
- Construction sequencing and traffic maintenance plans
- Coordination with agencies and utilities
Bridge Rehabilitation
When full replacement is not required, we provide rehabilitation solutions that extend the life of existing structures and maximize return on investment. Our rehabilitation services include:
- Structural strengthening and retrofitting
- Deck repair, overlay, and joint replacement
- Corrosion mitigation and protective coatings
- Substructure repair for timber, steel, and concrete elements
- Load rating updates after rehabilitation
