Interstate weight limits

Federal law sets the Interstate limits at 20,000 lb on a single axle, 34,000 lb on a tandem, and 80,000 lb gross, with the bridge formula on every axle group (23 CFR 658.17). States may keep higher limits they had before the federal limits took effect ("grandfather rights").

Grandfathered: up to 95,000 lb GVW for longer combinations on listed National Network routes, including I-80 from Wyoming to Exit 440.

FHWA on Nebraska: Nebraska has a grandfather provision under Federal law (23 CFR Part 658, Appendix C) to allow vehicles to operate up to 95,000 lbs. GVW on parts of the Interstate System. See the Routes section for a full description of the routes to which this grandfather provision applies.

Bridge formula check with Nebraska limits

A 5-axle tractor-trailer is filled in. Change the spacings and weights to match your rig; the limits for single axles, tandems, and gross are Nebraska's Interstate limits.

Axle spacings

Center of one axle to the center of the next, in feet. Axle 1 is the steer axle. 4 ft 6 in = 4.5.

Axle weights (optional)

From your scale ticket. Leave all blank to see the limits only.

Your result

Enter your axle spacings and tap "Check bridge formula". A 5-axle tractor-trailer is filled in.

Where Nebraska allows more than federal limits

Height, width, and length

Over these limits you need a permit. Nebraska oversize/overweight permits (402-471-0034).
