More growth and more jobs are expected in Huntsville by the FBI in the coming years, U.S. Sen. Richard Shelby said Monday, as construction continues on a sprawling campus inside the gates of Redstone Arsenal. Shelby, speaking to about 900 business and community leaders at a Huntsville/Madison County Chamber of Commerce breakfast, said the FBI investment could eventually reach $1 billion.

Such a project would be on par with the Mazda Toyota Manufacturing USA development in Huntsville, which promises a $1.6 billion development and 4,000 jobs.“Huntsville is on fire,” Shelby told the breakfast audience at the Von Braun Center. “

In November, the FBI announced the transfer of 1,350 jobs to Redstone Arsenal.

The expansion of the FBI presence at Redstone Arsenal is expected to ultimately be more than 4,000 jobs.
