Route the main line is 72.6 km in length, using a two-way six-lane expressway standard design of the design speed of 120 km / h. The same period in construction the Handan, Linzhang, Chengan, Quangping, Weixian name 6 cable length of 69 kilometers. The total investment of 7.8 billion yuan. AK0 +868.115-Ramp Bridge is located Chengan interchange at i = +3.4% of the uphill sections of interoperability within the ramp overpass, the bridge longitudinal, R = 3500m convex curve, and i = -3.0% downhillon. Plane at A = 170m left to ease the curve and A = 165 in the right partial transition curve. Span combinations as follows: 4 * 25m +4 * 25m, a total of two copies. Bridge superstructure of prestressed box girder bridge width 19.5m, full-bridge length of 206.0m. The bridge across the Han large (Handan - name) highway, cross Stake AK0 +868.114 = K7, +792.915, angle is 80 o, clearance 5m. The Bridges of prestressed concrete continuous box girder structure, the cross section of single-box three rooms. The beam height 140cm, boom length 200.0cm, cantilever the root of the thickness of 45cm, the web thickness of 50 to 80cm, roof thickness of 25cm, bott
