Collapse through Huihe Beiguan landscape Avenue all steel bridge were installed Size 34 pieces of bridge deck steel, the longest span 22.5m, the most important bridge deck steel for the 68T. STC concrete 4000m2, STC concrete has the characteristics of high compressive strength, good resistance to bending strength, high strength, high toughness, and more remarkable characteristic is that it is linear expansion coefficient close to the plate, which is easy to be combined with the surface of the steel beam. At present, the bridge anti-corrosion paint brush, landscape trails have been installed.
Runs through the north and the south in the core area of the canal in Tongzhou City Beiguan Avenue (northbound West Binhe Road Tong Yan Road) East North West Binhe Road, the starting point is located in the west side of North Canal, north to Tong Yan of the high-speed, the road design, with a total length of 1647.84 meters.
