Preserving Bridge Infrastructure
Bridges require ongoing repair to protect transportation safety and keep road and railway networks operating without disruption. Even well-designed bridges sustain damage over time through environmental exposure, heavier traffic loads, and unexpected events. Timely repair and protection preserve the structural integrity of aging infrastructure and extend its service life.
Common bridge types we service: Roadway bridges, railway bridges, reinforced and prestressed concrete bridges, steel bridges, girder bridges, stay cable bridges, arch bridges, truss bridges, and more.
- Aging materials (concrete, steel, timber, masonry)
- Cracking or spalling from alkali-silica reaction
- Carbonation of concrete
- Chloride penetration
- Chemical exposure (pollution, acid rain)
- Freeze-thaw cycles
- Change in use or increased loads
- Clearance or regulatory updates
- Material fatigue from traffic
- Creep, shrinkage, or settlement
- Missing or damaged expansion joints
- Design or construction defects
- Overloading
- Ground movement or earthquakes
- Excessive vibrations
- Fire or flooding
- Collisions
Comprehensive Solutions for Bridge Repair
Structural Analysis and Solution Design
Structural analysis is the first step of every bridge repair project, including deck rehabilitation assessments. Our team combines engineering expertise with on-site inspection and testing to determine the most effective repair or strengthening approach, from conceptual design and material selection to staged construction services.
On-Site Repair and Strengthening
Our construction crews perform all on-site repair and strengthening, using specialized equipment with traffic management support as needed. We manage structural steel reinforcement and construction projects with field-tested materials that deliver safe, long-lasting results.
Inspection and Maintenance
Inspection and maintenance protect the structural integrity of every bridge repair investment. Our services include routine inspections, structural assessments, and health monitoring to detect damage early. We support state DOTs and public agencies with emergency response and preventive maintenance for bearings, joints, cable stays, and tendons.
Bridge Repair Solutions and Technologies
Freyssinet’s bridge repair and rehabilitation services, delivered as an experienced bridge contractor, cover post-tensioning systems, cable stays, bearings, and expansion joints, including major rehabilitation replacement projects on aging structures. These solutions reduce the long-term cost of bridge ownership and give new service life to infrastructure that may need targeted repair before full replacement becomes necessary.
