The route runs along the existing dyke top road on the west bank of the Liangji Canal, connecting the existing Binhe Boulevard to the north and the existing Binhu Boulevard to the south. The main bridge adopts a span arrangement of (35+65+220+65+35) meters and is the largest two-pylon cable-stayed bridge in Jining City.
The bridge was completed and opened to traffic in December 2024, with 12 sets of longitudinal viscous dampers and 12 sets of transverse metal dampers applied. The models and parameters are as follows:
Model | Damping Force（kN） | Displacement（±mm） | Qty（set） |
FVD-2000/±300 | 2000 | 300 | 12 |
TSDD-H1200-1750-e300-ei240 | 1200 | 300 | 12 |
