Silver Bridge Design loads
At the time of its construction, a typical family automobile would be the Ford Model T, with a weight of about 1,500 lb (680 kg). The maximum permitted truck gross weight was about 20,000 lb (9,072 kg). At the time of the collapse, a typical family automobile weighed about 4,000 lb (1,814 kg) and the large truck limit was 60,000 lb (27,216 kg) or more. Bumper-to-bumper traffic jams were also much more common - occurring several times a day, five days each week.
