In the past decade, Louisiana Tech built new buildings and renovated some of the Main Campus' older buildings. The university erected Davison Hall (home of the university's Professional Aviation program), the Micromanufacturing Building, and the Biomedical Engineering Building on the south end of the Main Campus along Hergot Avenue. Tech tore down the old Hale Hall and constructed a brand-new Hale Hall in the style and design of the predecessor in 2004. On the eastern edge of the campus, the university renovated the building now known as University Hall, redesigned the bookstore interior, and made needed repairs to Keeny Hall and Howard Auditorium. All of the major athletics facilities on the north part of the Main Campus have received major upgrades and renovations in the past five years.
