The site is 15 blocks west of Interstate Highway 35 West and 15 blocks north of Interstate Highway 30 as they pass through the city. Gunn & Curtis designed this Texas Renaissance Revival facility. A Justice Center built in 1990; a Criminal Courts Building built in 1962; an Administration Building built in 1983; a Family Law Center in 2005; and a Civil Courts Building built in 2015 all augment the courthouse.
