There are 3 canals under construction located on roads around mountain slopes and in low-lying areas in Hong Son and Giang Son Dong communes (Do Luong) with a total length of nearly 2km.

This is a project to repair and supplement the road drainage system at urgent locations on the National Highway invested by the Nghe An Department of Transport.

The ditch system is designed as an open ditch assembled with precast concrete. The ditch surface is 1.2m wide, the bottom is 0.4m, poured with fresh concrete, the beveled edge is 0.56m, and the height is 0.4m. In the sections with ditches, the road surface is widened by 1m, paved with stone and poured with fresh concrete.

Construction is expected to be completed by May 15, 2018.
