Work started on November 18 on a tunnel route under the Ca Pass that will link the two central provinces of Phu Yen and Khanh Hoa as well as reduce traffic accidents along National Highway 1A.

The tunnel road, from Phu Yen province's Hao Son commune to Khanh Hoa province's Co Ma commune, will be 13.4km long. The maximum speed for vehicles travelling along the route will be 80kph.

The project has total investment capital of VND15.6 trillion (748 million USD).

At the ceremony to mark the start of construction work, National Assembly Vice Chairman Huynh Ngoc Son said that the Deo Ca Investment Joint Stock Company, as the project's investor, was required to complete the tunnel by 2016.

On completion, the tunnel route is expected to reduce traffic accidents on National Highway 1A and contribute to the development of large economic centres, industrial zones and tourism sites in the central region.

The work will also contribute to socio-economic development and better ensure security in the central and Central Highlands region.-VNA
