BLOUNTVILLE — Northeast State Community College’s latest building project, the Technical Education Complex, remains the most expensive community college capital project in Tennessee history. But NSCC and Sullivan County Schools officials are looking to the future, beyond completion of the nearly $30 million project in the spring of 2020. That’s because it will be the new home for programs in career technical education for secondary and post-secondary students, as well as for workforce training, replacing the two outdated, original NSCC buildings from the school’s founding in 1966. Construction crews Thursday morning placed the final steel beam and set the “topping out” evergreen on the skeletal framework of the $29.8 million project.
