Seven people were killed when the bridge was hit by a crane carrying 1.5t of steel. However, initial reports that the bridge collapsed now appear to be unfounded.
It is now understood that the steel hit an adjoining wall, causing it to cave in and crush the workers.
Dubai police chief Dhahi Khalfan Tamim said at the time of collapse that it was his "tentative assumption" that the bridge collapsed because a crane driver had tried to lift a 1.5 tonne load of steel onto the bridge and that the load hit against the bridge columns "causing it to collapse".
"The fault is two-fold," he said. "[It lies with both] the driver's miscalculation of the height of the steel columns and a lack of site supervision."
Around 40 workers were on the bridge under construction on Sufooh Road, near Jumeirah Marina Mall, an area marked by high-rise residential and commercial buildings, when the accident occurred.
