The width is 62 feet of road plus 10 feet of side walk. So picture 36 people 150 pounds each across the width of the bridge. He said this was a "rapid calculation" for "where the crowd was thickest". | |

| May 9, 2023 at 13:38 | comment | added | DavePhD | @Lundin those trucks are about 72 feet long and 72,000 pounds, so only 1000 pounds per linear foot of bridge (for trucks touching end to end the all along the bridge in one lane). If all 6 lanes were covered with trucks end to end with no spacing it would be about 6000 pounds per linear foot of bridge. | |
| May 9, 2023 at 13:21 | comment | added | Lundin | "about 5,400 pounds per linear foot" I might be struggling with converting American units, but maybe someone could make a similar calculation for a heavy loaded truck carrying some 30-50 metric tons. Because I can't quite grasp how humans no matter how tightly packed or piled on top of each other can ever weigh more than a truck hauling something like construction machinery. Or maybe such heavy haulage trucks are not allowed to use the bridge? | |
| May 1, 2023 at 16:35 | comment | added | DavePhD | @Bobson that's not the design. The design is +10 to -1 feet. | |
| May 1, 2023 at 15:03 | comment | added | Bobson | I'm not quite sure the quotes support your last statement. If the design is to be able to support going from an arch of +6 to a sag of -6, then flattening it by 6 feet would, in fact, make it completely flat. | |
