Twenty-seven Yangtze River Bridge to do static load test.
Reporters on the scene saw, on the ground with the white line drawn N-mark. Unit weight of 30 tons of heavy vehicles was towed to these markers, the measurement of relevant data. 2 sets of each lane open on the car, some observational data.
32 960 tons of heavy vehicles were placed in various parts of the main bridge, like one huge Cold, meticulous staff to do the test, carefully recorded data,
It is reported that the night before twenty-seven bridge completed dynamic load test, is to use one or two cars, pull a few sets of heavy vehicles, to 5 km, 10 km, 20 km -50 km speed to open the line to check how the bridge to withstand by more than one vehicle is not parallel or stand fast by the test.

Q: Can you avoid the
A: 2734 is the most difficult bridge deck concrete and steel structure on the combination of this design, to avoid the pitch easily attached to the steel box on the slip road leading to frequent breakage. However, the same, take the truck is the highest bridge design standards. Bus 715 Road, 577 Road, you can also go twenty-seven bridge.
Q: Why is original three towers?
