The load rating is the maximum allowable weight the structure can be supported to hold without damaging the structure. Bridge inspections also include the investigation of weathering. This inspection is to identify and correct conditions that may lead to premature failure of the structure. Conditions that can cause this include extreme temperature changes, storms, ice, and debris.

Bridge inspection services in New York also include the detection of problems that can increase the risks of falling debris and cause damage to the deck of a structure.

NBIA is a non-profit association that was formed in 1966 to serve the interests of the drivers, builders, engineers and owners of toll roads in the National Interstate Highway Administration area.

Bridge inspections in New York include a comprehensive examination of the structure of the roadbed, superstructure, underbelly, and seepage of the roadway. The purpose of this is to ensure that the roadway is safe for the traveling public. Bridge inspectors will also look for damage that has occurred to the foundation or supporting structure of the bridge. They will check for leaks, seepages, cracks, deteriorated conditions, loose fixtures, missing or inaccurate equipment, missing connections, and other defects. Once these issues are addressed, an examination of the equipment found in the structure will be conducted.

Most bridges are built using steel that is galvanized to resist corrosion. However, galvanized steel does not always resist all forms of damage and aging. When a bridge inspection is completed it will indicate the degree of deterioration that exists and whether further repairs are warranted. Most states require periodic inspections to ensure that these types of defects are identified and corrected before the bridges are deemed safe for use.

In many instances, local, state, and federal transportation agencies request bridge inspections be performed at regular intervals. In New York City for example, the local traffic authority has the authority to require that a specific number of biennial bridge inspections be performed. If the number of such inspections is less than a certain percentage of biennium, the city may conduct additional inspections every four years. The goal is to detect problems earlier and remedy them before they significantly decrease the performance of the system. It is important for agencies to perform a comprehensive inspection since some types of bridges are considered more hazardous than others, which can include lack of structural soundness or failure.

The primary goal of an inspection is to identify problems, review the condition of the structures, discuss potential solutions, and then make determinations regarding what can be done to correct the problems. Bridge inspectors are usually made up of a team leaders who report directly to the bridge manager or the district office that is overseeing the maintenance on the specific bridges in question. Bridge inspection teams consist of a supervisor, bridge specialists, and operators. They perform evaluations of the condition of the bridges, concentrating specifically on defects that pose a threat to the integrity of the infrastructure. Bridge inspectors must use their observations and expertise to identify problematic issues before they can be addressed.
