(OP)
Is there such a thing as 16" concrete masonry units? I have seen 14", but am told in the US-midwest 16" does not exist.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: 16" cmu block
Standard Specification for Load-Bearing Concrete Masonry Units, ASTM C 90 is the most frequently referenced standard for concrete masonry units. ASTM C 90 includes minimum face shell and web thicknesses for the different sizes of concrete masonry units. Overall unit dimensions (height, width, or length) are permitted to vary by +1/8 in. (3.2 mm) from the dimensions specified by the manufacturer. Where required, units may be manufactured to closer tolerances than those permitted in ASTM C 90. ASTM C 90 also defines the difference between hollow and solid concrete masonry units. The net cross-sectional area of a solid unit is at least 75% of the gross cross-sectional area.
