The total length of the Xinshougang Bridge is 1.36km and the main spans is 639 m. The main span structure is a “non-classical” cable-stayed bridge; it’s a combination of cable-stayed and rigid-frame systems. The two towers are outward-inclined elliptic arches with different height and twisted curved tower legs; at the main span, the tower legs are connected by two box girders which are connected by floor beams supporting the steel orthotropic deck. The dimension of the two box girders varies in both vertical and transverse direction and the dimension are optimized for stress distribution by parametric study. The bridge has 5 spans in total; the span layout is 50m + 133.3/158.4m +280m + 120.28/95.1m + 56m. Since the Yong

ding River and Chang’An Avenue intersect obliquely with

a skew angle of 57.9 degrees, the tower foundations also follow this skew angle for bett

er flood discharge. The center line of piers is 25.10m away from the vehicular direction. The west tower is 124.5m high and the tower legs are moment-connected with the box girders and the piers; the east tower is 77m high and the tower legs are moment-connected with the box girders and supported by two 7800 tons anti-lock one-way ball-shaped vibration-absorption steel supports. The stay cables are set up in a harp-style with gradually varying space. The standard deck width is 47m with 8 motor lanes and 3.5m non-motor and 3.0m pedestrian lanes on each side. The maximum deck width is 54.9m. There is a separation between the motor and non-motor lanes. All the steel structure members were pre-manufactured in shop and transported to the field and assembled together by welding. The total quantity of the steel used is 45 thousand tons; the maximum crane lift weight is 750 tons; the total investment is 164 million dollars.

Project description

：

This project is the first bicycle express way with special right-of-way in Beijing, which serves the short distance commuter traffic between Huilongguan community and Shangdi high-tech park. The project is cleverly wired to connect large residential areas, commercial buildings, public transport hubs and high-tech parks. It will play a positive guiding and demonstration role in diverting short-distance commuter traffic, relieving the pressure of rail transit and promoting the construction of green transportation system in China.

The total length of the project is 6.5km, of which 2.74km is the length of the new roadbed, 2.72km is the length of the new bridge, and 1.04km is the current road. The design speed is 20km/h, the road surface is 6m wide, and there are 5 lanes in both directions (the middleis set as tidal lane). One maintenance area, one relay station and eight importand export stations are set up along the route, and the bicycle parking systemis set up simultaneously.
