The distance from ground to the bridge deck is more than 80 metres.
Featuring four lanes with a width of 14.5 metres, the total construction cost of the bridge is estimated at nearly VND500 billion (US$21.8 million).
With construction having started in 2020, the bridge spans more than 600 metres over a valley, connecting the foot and the top of a winding, dangerous local road known as three-storey slope.
The viaduct is part of the road linking the Noi Bai-Lao Cai Expressway to the resort town of Sapa, which is expected to cut the travel time between Lao Cai City and Sapa.
A boost to tourism in Sapa and reduction in traffic accidents on the treacherous slope are also anticipated.
