Where's the confusion? The end of the bridge is about 40-48 inches from the hinge point, depending on which end, so 59 lb-ft of torque would be between 15 and 17.5 pounds.

so say if using a window van motor with 25.8 ft-lbf applied to the end of the bridge? Would this tip the bridge or not?
How much force are you applying to the end of the bridge? A one-foot-long direct-driven rod perpendicular to the motor shaft could work. A two-foot-long rod would not.
