On July 16, Lai Chau Provincial Department of Construction issued Notice No. 3661/TB-SXD on supplementing the plan for temporary traffic diversion and organization at Km76+250, National Highway 12, in Chieng Chan village, Le Loi commune.
Previously, as Lao Dong Newspaper reported, due to prolonged heavy rain, the Km76+250 section on National Highway 12 experienced serious landslides, breaking the entire roadbed and surface, causing traffic through the area to be cut off.
To ensure traffic flow, the Department of Construction has issued Notice No. 3652/TB-SXD dated July 16, 2026 on organizing temporary traffic diversion.
According to the Department of Construction, to date, Provincial Road 127 (section from Nam Hang commune to Lai Ha bridge intersection), National Highway 32 and National Highway 279 have basically been repaired, meeting operating conditions. On that basis, the unit supplemented 3 traffic diversion plans for vehicles traveling between Lai Chau and Dien Bien provinces.

The second option, vehicles also follow National Highway 4D and National Highway 12 to Pa Tan commune, then turn into National Highway 4H to Bum To commune, continue to turn into Provincial Road 127 through Nam Hang commune to Lai Ha bridge intersection, then merge National Highway 12 to go to Dien Bien and vice versa.
