Oklahoma sets 20,000 lb on a single axle and 34,000 lb on a tandem, but states no gross weight figure whatsoever — § 14-109 incorporates the federal bridge formula by reference, so there is no Oklahoma number to quote. Height splits by road class: 13 feet 6 inches on county roads, 14 feet on turnpikes, Interstates and US or state highways.
