A sprawling business campus northwest of downtown Dallas just hit the market.

Trinity Industries’ former 11.5-acre office complex is up for grabs after the company moved to a new headquarters on the Dallas North Tollway in Farmers Branch.

The four-building property on Stemmons Freeway near the UT Southwestern medical district includes about 225,000 square feet of space.

Trinity Industries is moving to the International Plaza II building on the Dallas North Tollway.

Trinity Industries was one of the largest businesses in the Stemmons Freeway corridor before its move.

The largest portion of its old campus is a 10-story, 125,000-square-foot office tower at 2525 North Stemmons, which was built in 1974. Three smaller buildings and a parking garage also come with the deal.

Commercial property firm CBRE is marketing the buildings for sale.

“The property’s flexible zoning permits the highest density in the Medical and Design districts,” CBRE says in its marketing pitch. “Given the area’s transformational, ongoing development cycle exceeding $3 billion, the former Trinity Industries campus represents one of the most substantial redevelopment opportunities in Dallas-Fort Worth — the nation’s top market for growth.”

The campus is just down the freeway from where developers are converting the former Exxon Mobil office tower and surrounding buildings into a biomedical research and nonprofit business center.

The former Trinity Industries campus is more than 11 acres.
