By the early 1980s HTHS was still dealing with overcrowding, classes then moved to the new Trussville-Clay Road campus in January 1984, at which point the 1938 facility was renovated to house Hewitt-Trussville Middle School.

The front wing contained the gymnasium, auditorium, cafeteria, band room and administrative offices.

The rear wing contained academic classrooms with the five hallways being distinguished by color (the red, orange, green, yellow & gray).

During the late 1980s and early 1990s, HTHS struggled to accommodate a rapidly growing student population from the Trussville, Clay, and Chalkville areas.

By 1995, HTHS enrolled over 1,500 students[17] in only three grades and was the sixth largest high school in the state of Alabama.

[14] Although overcrowding was temporary resolved with the construction of Clay-Chalkville High School in 1996, the continued rapid growth within Trussville resulted in the need for a new building, which opened in October 2008.

On Tuesday, November 14, 2006, the Trussville City Council rezoned the parcels at 5601 and 5555 Trussville-Clay Road from agricultural to institutional use to allow for the construction of the new building.

However, more funding was required after a failed attempt to build an indoor swimming pool on the 2nd floor B-Wing.

[20] HTHS competes in AHSAA Class 7A athletics and fields teams in the following sports:[21] Jack Wood Stadium, adjacent to the building at 301 Parkway Drive, was used until 2013 for football games and track and field events, as well as annual commencement exercises.

HTHS sponsors a variety of student activities, including many nationally affiliated clubs and organizations.
