Clarksville, TN – Part of Cumberland Drive in Clarksville remains closed today after a road cave-in caused a sink hole. Officials say the cave-in was caused by a break in an underground water main. The lane heading up Cumberland Drive off of Riverside Drive and across from 48/13 is still closed and will remain so for some time. The merge ramp off of the 41A Bypass onto Cumberland Drive is still open.
