In the design, construction, and operation of any bridge, there are many technical details that require close inspection and thorough documentation to ensure its safety. One such detail is regular inspection of the bridge during all stages of its life, including during construction and once it’s in operation. There are specific inspection requirements during each […]
When you think of railroad bridge inspections, you might envision inspectors in hard using big trucks and other railroad bridge inspection equipment to test the structure’s integrity. While that accurately represents what these inspections entail, there is a lot more work that goes into it than that. Inspectors must be knowledgeable about different types of […]
Bridges, like people, require maintenance as they get older. And the United States has plenty of aging highway bridges. According to the most recent Infrastructure Report Card published by the American Society of Civil Engineers (ASCE), there are more than 617,000 bridges across the United States. However, more than 42 percent of those bridges are […]
Have you ever wondered why traffic control personnel use a particular type of traffic control device in a given situation? If so, you are not alone.

Bridge deck inspections are a significant component for many DOTs or the firms they employ for that purpose.

Responsibility for the regular inspection of these highway […]
Bucket trucks have a long and interesting history. Over the years since their inception, bucket trucks have been referred to by many names, including cherry pickers, aerial lifts, man-lifts, and boom trucks. In addition, they’ve been called elevated work platforms, aerial work platforms, and basket cranes. In the heavy equipment industry, the larger capability telescopic […]
Road construction, repairs, and maintenance – including that done on highway bridges – almost always requires a temporary traffic control set up. This can range from a small flagging operation, to a large scale lane closure consisting of TTC signs, arrow boards, message boards, barricades, and truck mounted attenuators. Temporary Traffic Control (TTC), also referred […]
Routine bridge inspections are often anything but “routine.” For most people, engineers included, there is nothing routine about being suspended 175 feet above a green, valley floor. And this in a metal basket attached to the end of a thin, steel boom that’s been lowered from the relative safety of a bridge deck! When you’re […]
Depending on the industry you’re in, the term “bucket truck” might bring to mind different things.
