A bridge inspection checks that a bridge is still doing its two jobs: carrying the traffic on it, and letting water, roads or rail pass beneath it. This template is for a routine visual inspection — the kind a county road department, park, campus, private estate or contractor makes between formal inspections, after a flood, or after a truck strike. You walk the bridge element by element, rate each one Good, Fair, Poor or Critical, photograph what you find, and finish with summary ratings and a list of maintenance work. Any Poor or Critical element lands in the report's summary of findings. Fill it in here and download a PDF without an account, or speak while you walk, and the document writes itself.
What this inspection is, and what it is not
In the US, public highway bridges get formal safety inspections under the National Bridge Inspection Standards, led by a qualified team leader, usually every two years, with load ratings and underwater dives where needed. This form does not replace that. It records a routine visual look at what can be seen from the deck, the banks and safe access points, by someone who knows what to look for.
That routine look is still valuable. Most bridge problems — a blocked drain, a loose joint plate, a scoured footing after a storm, a guardrail end clipped by a plow — start small and are cheap to fix if someone notices them between formal inspections. Owners of private and park bridges, which often sit outside any formal program, may have nothing else.
Walk it in the order you meet it
Start where a driver starts: the approach roadway, the bump at the bridge end, the guardrail and where it joins the bridge rail. Then the deck and its surface, the joints and drains, the railings. Go below for the beams or girders, the bearings that let them move, and the abutments and piers that hold everything up. Finish in the channel, looking upstream and downstream.
Each element gets a rating and, where it is anything but Good, a photo and a line about what you saw and exactly where. "Spalling, 2 ft by 1 ft, exposed rebar, south fascia of span 2" is a finding someone can act on; "some concrete damage" is not.
Water is the usual enemy
More bridges are lost to scour — the river carrying away the soil around footings and piles — than to anything else. Scour is worst during floods, when nobody can see it, and the hole may partly refill as the water drops. Look for exposed footings or piles, hollows beside the supports, slumping banks, debris piled against piers, and signs the water has reached the beams.
Water on the deck matters too. Blocked drains and leaking joints send salty runoff over bearings, beam ends and pier caps, which is where corrosion and spalling usually start.
From ratings to a maintenance list
Element ratings feed a set of 0–9 summary ratings for the deck, the superstructure, the substructure and the channel, chosen by the inspector rather than computed. A summary rating of 4 or lower, or any Critical element, is a finding, and the form asks whether the owner was told the same day.
The maintenance list turns findings into work: clean the drains, reset the joint plate, replace the damaged guardrail end, place riprap at pier 2. Each item carries a priority and an owner, so the next inspection starts from a list of what should have been done.
Common questions
Who can carry out a bridge inspection?
Formal inspections of public highway bridges in the US must be led by a qualified team leader as set out in the national standards. Routine visual checks like this one are usually made by maintenance supervisors, engineers or trained staff working for the owner. Whoever inspects should know the bridge type and stay off anything that is unsafe to reach.
How often should a bridge be inspected?
Formal highway bridge inspections are typically every 24 months, more often for bridges in poor condition. Routine visual checks are often made yearly, and always after a flood, an earthquake, a vehicle or vessel strike, or a report from the public.
What do the 0–9 condition ratings mean?
They are a general scale for a whole component: 9 is as new, 5 is fair with some section loss or cracking, 4 is poor, 2 is critical, and 0 means failed. This form uses that scale for summary ratings in its own words. Use your owner's or agency's coding guide when the ratings feed an official record.
What should I do if I find something critical?
Tell the bridge owner straight away, by phone, and record who you told and when. If the bridge may not be safe to use, the owner decides whether to close it or limit loads. Do not wait for the written report.
Can this form be used for culverts or footbridges?
For footbridges, yes: rate the elements that are present and mark the rest Not present. Large culverts have their own items — barrel, headwalls, inverts — and are better served by a culvert form.
Does this cover drone inspections?
This form records what the inspector sees and photographs, from whatever access is safe. Photos taken from a drone can be added to any photo field, but the form is not a flight log.
