The $740 million project is expected to reduce travel times by 40 minutes.

The Deo Ca Tunnel under its namesake pass on National Highway 1A will open on Monday. The tunnel runs more than four kilometers from the central province of Khanh Hoa to the neighboring Phu Yen. 


The second longest road tunnel in Vietnam, after the one running under the Hai Van Pass, is expected to cut the travel time by 40 minutes and reduce traffic accidents. Deo Ca is one of the highest and toughest mountain passes in Vietnam, where drivers face constant risks of crashes due to its steep slopes and blind corners. In April, two crashes caused a tailback of 10 kilometers.
