to a defining chapter in Irby Construction Company history.

In 1969, Irby completed the first 765 kV transmission line built in the United States, a 31.5-mile line constructed for American Electric Power in Kentucky. In the years that followed, Irby built more than 900 miles of 765 kV line across Ohio, Indiana, and West Virginia, ultimately constructing more than 90% of America’s 765 kV grid.

Nearly six decades later, we’re proud to be working with AEP again and continuing a relationship built on trust, quality workmanship, and a shared commitment to strengthening America’s electric infrastructure.

Our longtime motto and mission at Irby Construction Company is Absolute Performance. It's the standard we hold ourselves to every day: showing up, working with purpose, and taking ownership of every outcome.

That commitment was front and center on July 12, when superintendents and field leaders from across Irby gathered in Jackson, Mississippi, for our annual Superintendents' Meeting where our leaders and guest speaker Paul Walker reinforced the ownership mindset and leadership that continue to drive our success.

There’s nothing quite like bringing the Legend Foundation Services Cooking Team to the table! 🍽️

Legend, a division of Irby Construction based in Geismar, Louisiana, recently rolled its mobile kitchen up to Irby HQ in Richland, Mississippi, serving up a lunch that brought a little taste of Louisiana for all:
🦞 Crawfish Étouffée
🐟 Fried Catfish
🥔 Potato Casserole
🐷 Pulled Pork Sandwiches
🤠 Cowboy Beans

For Legend, cooking for others is about more than a good meal. It’s become another way to show up, build community, and take care of people, whether that’s feeding families and volunteers after a disaster or feeding coworkers across the Southeast.

Thank you to all who showed up and showed out!
