New technology helping track Harvey as Austin TxDOT crews head south

AUSTIN (KXAN) —  As Tropical Storm Harvey moves closer to Texas, the state is expected to raise its preparedness level.

TxDOT crews out of South Austin are packing up to mobilize ahead of the storm. About two dozen crew members will migrate south to a staging area in San Antonio. After the storm hits land, they will determine where to go to clear roadways so people and emergency responders can get through.
