The Need: The bridge that crosses the Ohio River on US 421 is deteriorating and needs replacing. Closing the bridge for construction is an inconvenient option, to be avoided if possible.

The Answer: A unique construction method called “truss sliding” enables construction to carry on while leaving the bridge accessible for all but 10 days of the construction process.

VS Involvement: VS provided inspection services throughout the project, including daily on-site inspections, sampling, Quality Control, written reports and documentation, tracking of progress, safety maintenance, and all project close-out reporting.
