General Information
Figure 1 shows a pedestrian suspension bridge.

Type | Three-span suspension bridge |
Main span | ≅ 45 m |
Deck width | ≅ 1.5 m |
Deck width to main span ratio | ≅ 1:30 |
Pylon | Steel and reinforced concrete (H-shaped) |
Girder | Steel longitudinal beam |
Girder-Pylon and Girder-Abutment Connections
Figure 2 shows the girder in the pylon region.
![Girder in the pylon region](bridges/suspension-bridges/bridge-22/2-pylon-girder.jpg)
The girder is not connected to the pylon. Figures 3 and 4 show the girder in the abutment region.
![Girder in the abutment region](bridges/suspension-bridges/bridge-22/3-abutment-girder.jpg)
There is no connection between girder and abutment.

Wire Rope End Termination
Figure 5 shows two hanger cables at their bottom ends.
![Hanger cable termination using U-bolt clamps](bridges/suspension-bridges/bridge-22/5-hanger-end-fitting.jpg)
The hanger cables are made of steel wire ropes, and the end termination consists of U-bolt clamps. The saddle parts are on the dead end of the cables, while the U-parts are on the live end of the cables. The number of U-bolt clamps per hanger cable is not equal: two on the left hanger cable, and three on the right hanger cable. There are no wire rope thimbles between the plates and the hanger cables.
