AT&T broke ground on a $1.3 billion headquarters campus in Plano, built on the former Electronic Data Systems site on Legacy Drive. The campus will bring all of the company's Metroplex offices together in one location.

Why it matters

The project concentrates a large corporate workforce in a single Plano campus, which could shape local commuting, real estate and business activity around the site. Consolidating offices across the Dallas-Fort Worth region reflects how the company is organizing its operations in the area.

The $1.3 billion campus spans 54 acres and is designed to accommodate 10,000 workers. The extraction does not specify the technical infrastructure or networking capacity beyond the installation of the campus's first fiber connection during the groundbreaking.

The players

AT&T

AT&T is a major American telecommunications company whose network and wireless services reach consumers and businesses nationwide.

The details

The campus site was cleared by imploding the former Electronic Data Systems buildings on Legacy Drive earlier this year. The groundbreaking included installation of the campus's first fiber connection, and construction on some buildings is expected to start on Dec. 1.

The Tech Race

The groundbreaking's first fiber connection ties the new headquarters to AT&T's ongoing fiber-optic build-out, the core of its network strategy. Placing the campus within that effort shows how the company is extending its infrastructure investments into its own operations.

Plano residents and commuters near Legacy Drive should expect construction activity beginning in December and continuing through 2029. The consolidation of AT&T's Metroplex offices into one campus will change where many employees work, which may affect local traffic patterns.

The takeaway

AT&T's Plano campus will concentrate 10,000 workers in one location once it opens in phases starting in 2028. For residents and employees, the project signals a long construction period and a significant shift in where the company's Dallas-Fort Worth workforce is based.

What happens next

Construction on some buildings is expected to begin Dec. 1, 2026, with AT&T targeting partial campus openings in the second half of 2028 and some buildings expected to be finished by March 2029.
