GAINESVILLE, Va. (CBSDC) - Route-29 Northbound is closed in Gainesville as firefighters continue to douse a burning church that went up in flames Friday morning.

Route-29 has partially reopened in Gainesville, with Southbound lanes now moving and Northbound lanes still closed near Linton Hall Road.

The large fire took hold of Mount Pleasant Baptist Church in the early morning hours. The fire has been extinguished but authorities are on the scene investigating and firefighters are still making sure the fire is completely out.
