With its design speed of 80km / h and two-way four-lane , The length of this road is 2800 m . The design includes plane design, vertical section design, cross section design, roadbed and retaining wall design, subgrade and pavement selection mix formulation and checking design and structure layer thickness of the waterproof and drainage design, culvert design, pavement materials. Graphic design with a flat curve, longitudinal section design with a vertical curve. Subgrade width of 24.5m, maximum superelevation 6%. Subgrade and pavement drainage facilities in a ditch, ditches, drains, and so on. The bridge and roadbed width, using prefabricated prestressed concrete continuous box girder bridge. A culvert two, respectively for the reinforced concrete box and reinforced concrete pipe culvert. A culvert two, respectively for the reinforced concrete box and reinforced concrete pipe culvert. Pavement design includes determining thickness and structure design of pavement type, the design of pavement with asphalt concrete pavement, pavement structure design of 5 layers are fine 4
