Engineers Built a Bridge Inspection Training App in Three Days. It Could Help Fix America’s Decades-Long Infrastructure Crisis.
America has more than 600,000 bridges, and a growing number are approaching the end of their useful life. More than a third, some 220,000, need major repairs or outright replacement, according to the American Society of Civil Engineers, which gave the nation’s bridge infrastructure a C grade in its 2025 Infrastructure Report Card. And thereās more: The engineers trained to do the work are retiring and not being replaced fast enough. “Not enough new engineers and inspectors are entering the workforce to keep up with the rapidly growing demand for their skills,” says Barritt Lovelace, vice president of emerging technologies at global engineering firm Collins Engineers. A three-day hackathon in London offered a glimpse of a solution to start chipping away at the crisis. In May, Lovelace joined forces with Bentley Labs at Bentley Systems’ London office with a single goal: build an intuitive, virtual bridge-inspection training platform. The team used GitHub Copilot, an AI coding assistant, and a technique in which developers guide AI to generate software through natural-language prompts. And in just three days, they built what had previously taken six months. The result is a training app that bridge inspectors anywhere in the world can use to
