Bridge Formula Information

Federal Bridge Formula (US)

W = 500(LN/N-1 + 12N + 36)
  • • W = Maximum weight in pounds
  • • L = Distance between outer axles in feet
  • • N = Number of axles in group

Quebec Bridge Formula (B.47)

M = k(B + V(L + 20)²)
  • • M = Maximum mass in kilograms
  • • B = Base mass (18,000 kg)
  • • L = Wheelbase in meters
  • • k = Route class factor (1.0, 0.9, 0.8)
  • • V = Axle factor (0.0018-0.0027)
