Beginning October 29, a load test has been conducted at night on the East Sea Bridge, which links Shanghai to the under-construction Yangshan Deep-Water Port.
Last night, 24 container trucks, each weighing 55 tons, passed across the six-lane bridge in over 20 different patterns as designed by the testing staff.  The staff recorded data at seven observation points and will report them to bridge experts in the middle of this month, when the experts will appraise the overall structure of the bridge.  Appraisal on individual sections has already been completed.
The load test is carried out at night so as to minimize errors arising from fluctuating temperatures during daytime.
