Suramadu Bridge was planned and had operated in the middle of 2009. The bridge located at a site of high enough
wind speed, accommodated movement of four-wheel vehicles and motorcycles. Therefore, an insight study related to aspects
of the bridge user’s safety and convenience needed to be done. Vehicles, which will pass the bridge, will get an impellent
due to wind. A huge impellent will be felt on the highest part of bridge is cable stayed of bridge. Based on data, on the wind
speed at bridge deck, there was a possibility that the wind speed at the bridge deck exceeded 15 m/s. Thus, the speed limit
for four-wheel vehicle was necessary to be done. On that case, the bridge operation must be equipped with a monitoring and
warning system which will automatically informed wind speed, and steps which must be done by the bridge operator. Another
alternative was by providing a wind shield on the bridge. The consequence was an aerodynamic study on the wind shield
form which will be installed, was needed to ensure the aerodynamic performance of bridge. The third alternative was that a
study on the aerodynamic stability of cable stayed bridge with a wind tunnel test was needed. Last alternative was a testing
of Section Model Test could be done by modifying bridge model, which had previously been used in a technical study, so that
it could save testing cost
