Not true.  See the Manual on Uniform Traffic Control Devices
(mutcd.fhwa.dot.gov) for the full details.  (The MUTCD requires that
Interstate designations be signed first, in numerical order, followed
by U.S. Routes, followed by state routes, followed by county routes.)

The "128" situation is a result of the FHWA's northeast district
office inventing its own rules rather than applying the national
standard.
