Bridge Inspections

Safety? Check. Reliability? Check. Extended service life? Check. For bridges of every size, type and material, we can help you conquer your inspection and maintenance goals.

Safer crossings. Fewer closures. Reduced maintenance, reconstruction and replacement costs. A rigorous bridge inspection program can offer innumerable benefits. But to realize them, you need a firm that knows how to do it right. Over four decades, Thornton Tomasetti has built an unrivaled reputation for excellence and accuracy in bridge inspection. And we’re more familiar than any other firm with the regulations governing the inspection of bridges.
