Crane and heavy-lift incidents
Setting girders and segments with large cranes creates overturn and dropped-load exposure with catastrophic potential.

Bridge Contractor Insurance
Your worksite may sit above a road or channel that remains open. Protecting the bridge in progress does not replace liability coverage for the traffic passing underneath.
The Southern Agency can review your bridge operations, traffic responsibilities and owner requirements against appropriate insurance.
Industry overview
You build or rehabilitate highway, rail or pedestrian spans, with duties that may include foundations, girder lifts and temporary supports. Where a road or channel stays open, a dropped load can affect travelers as well as your crew and the unfinished bridge.
The Southern Agency can review your specific bridge-building operations, including your lift plans and falsework designs, to help select appropriate insurance. We can help you identify which coverage protects your equipment and crews during risky maneuvers and how to align your policies with the insurance requirements set by public owners.
Risks worth discussing
Falsework and formwork failure
Temporary supports for decks and spans can fail under load, endangering crews and the structure under construction.
Falls from elevated work
Crews working on piers, decks, and steel at height face serious fall exposure throughout bridge construction.
Traffic maintained under active work
Keeping roads, rail, or water open beneath a worksite exposes the traveling public to dropped material and incidents.
Work over water
Building piers and spans over rivers and channels adds drowning, vessel, and pollution exposure to the project.
Damage to the structure in progress
A bridge under construction is exposed to collapse, storm, and flood loss before it is finished and accepted.
Bonding and public-contract terms
A public contract may require performance or payment bonds and specific limits. Check actual bid, award and ongoing obligations; satisfying a contract condition does not make every defect or delay insured.
Coverage worth discussing
Policies to ask about. Which ones fit depends on your operations, your contracts, and the carrier’s forms.
- General Liability InsuranceMay provide coverage for third-party injury or property damage caused during operations, including incidents affecting traffic beneath a bridge site.
- Workers Compensation InsuranceMay provide qualifying employee benefits for falls, lifting or struck-by injuries. Actual shore, barge and vessel duties determine the state-compensation, possible Longshore and vessel-crew review; an over-water job location does not select one answer for every worker.
- Builders Risk InsuranceMay provide coverage for physical loss to bridge work in progress, with terms varying by project and including specific conditions for collapse, flood, or storm damage.
- Business Auto InsuranceMay provide liability coverage for trucks hauling steel, segments and equipment, with mobile-equipment terms requiring separate review.
- Inland Marine InsuranceMay provide coverage for cranes, rigging and formwork moved between worksites.
- Surety BondsMay provide bid, performance, or payment bonds required by public contracts, with separate indemnity requirements for the contractor.
- Environmental Liability InsuranceMay provide coverage for cleanup and liability from fuel or material releases into waterways, though coverage depends on whether the source is a vessel, vehicle or cargo.
- Umbrella / Excess Liability InsuranceMay add excess limits for liability, though these limits do not extend to property losses for the bridge or cranes, or to excluded pollution or professional services.
Situations to think through
These hypothetical examples are not agency claim results. Whether a loss is covered depends on the facts, policy terms, and applicable exclusions.
Hypothetical: Girder set goes wrong over traffic
Hypothetical: during a beam set above an open road, a load shifts and damages property below. General liability may address covered third-party damage. Damage to the girder, crane or bridge work needs separate review, along with the crane-hire agreement and responsibility for the lift.
Hypothetical: Falsework fails before a pour
Hypothetical: temporary supports give way before a deck pour and damage the unfinished structure. Builders risk may address covered damage to insured project property. Check temporary works, faulty-work and collapse provisions and each party's insured interest rather than assuming the same terms pay both to correct a support and repair resulting damage.
Hypothetical: Fuel reaches a river during pier work
Hypothetical: equipment over water releases fuel into the river and triggers a cleanup demand. A pollution policy may address a covered release. Identify whether the source is a vessel, land equipment or cargo and review the corresponding terms; an environmental policy name alone does not confirm every marine release.
Before you talk to an agent
Questions to raise
- Describe each bridge operation, including rehabilitation, pile driving, cofferdams, girder setting, concrete work, and any erection engineering; do not rely on the business name to define the insured work.
- Identify who maintains road, rail, pedestrian, and vessel access during work and who can authorize closures.
- Have worker duties and locations reviewed for state compensation, possible Longshore obligations, and vessel-crew liabilities when operations involve navigable water.
- Review fuel, wet-concrete, and disturbed-sediment releases with the pollution policy's actual covered operations and exclusions.
- Schedule cranes, rigging, and rented equipment by value; ask about afloat equipment and distinguish equipment damage from damage to the bridge being built.
- Review any design or temporary-works responsibility with the agent even if professional liability is not listed among the initial policy suggestions.

Questions owners ask
What insurance does a bridge contractor need?
Compare liability for public injury or damage, actual crew benefits, road vehicles, equipment and bridge property separately. Waterway releases, engineering duties and public-owner bond requests need their own review. The mix depends on actual operations and contract obligations; a policy list or certificate does not confirm every lift, worker or design duty is insured.
Is the bridge covered while under construction?
Builders risk may help protect work in progress against collapse, storm, and flood loss before completion, subject to policy terms and flood or named-storm provisions.
Are bonds required for public bridge work?
Read the actual public bid and contract, obligee and timing for performance, payment or bid requirements. Performance and eligible supplier or subcontractor payment are different bonded obligations, subject to approval and capacity review. They are not the contractor's accident insurance, and indemnity can require reimbursement to the surety.
Does insurance address work over water?
Over-water work raises drowning, vessel, and pollution exposure that may need specific terms or endorsements. Coverage availability depends on underwriting and how the operations are described.
How is liability handled with traffic kept open?
Maintaining traffic beneath active work increases third-party exposure. General liability may respond to covered incidents, depending on policy terms, traffic-control practices, and the facts.
How is bridge contractor insurance priced?
Pricing commonly reflects span types, crane and falsework use, over-water work, payroll, bonding, equipment, and claims history. A tailored quote reflects how your specific operation works.
