Construction of 98 metre high abutments, the highest in the country, started in May 2007 and the bridge is expected to open to traffic in July this year.

The 918 m long, 9m wide bridge was designed at an estimated capitalisation of VND740 billion (US$43.5 million) invested by the Ministry of Transport.

Addressing the ceremony on April 18, Transport Minister Ho Nghia Dung said the project will create a nearest link between the two northwestern provinces of Son La and Lai Chau to meet the needs for socio-economic development and national defence in the region.
