HISTORY

WE’RE PROUD OF OUR RICH HISTORY AT IRBY

It’s hard in the business of building electric power infrastructure to have a history deeper than Irby Construction Company. We’ve been building electric power transmission lines as long as anyone. In fact, Irby crews built much of the existing electric grid and broke new ground on many industry firsts. The tradition continues today as we work to expand the grid’s capacity and apply new technologies for the future. Click on the timeline below to explore our proud past year by year.
