Benefit-cost analyses in the sizes and weights report support the economic justification, on the Federal-aid Highway Systems, of increasing the single axle weight limitation to 26 kips with accompanying tandem axle weight limitations going up to 44 kips. Gross loads could either be increased to 120 kips or no gross load specified and instead axle weight and spacing employed as the control. The estimated increase in construction and maintenance costs for the Federal-aid Highway Systems resulting from such an increase in axle weight limitations would be $297 million. The corresponding estimated annual reduction in truck operating costs would be $3.61 billion, or more than 12 times the cost.
