The paper presents 15 GHz Very Large Array observations of the luminous double radio galaxies 3C 166 and 3C 411. The data confirm the spectral steepening in the lobes of both sources indicated by previous lower-frequency observations. The spectral steepening is interpreted as being due to synchrotron-radiation losses (synchrotron aging) and is used to infer a radiative age for electrons in both lobes of 3C 411 and the southern lobe of 3C 166. The results are presented as a relative speed of separation between the hot spot and a parcel of lobe material. The speed estimates, in the range of one to a few times 10 to the 4th km/s, are comparable to values determined for other radio sources. The observations also suggest that for both sources geometric depolarization is responsible for the reduction in fractional linear polarization at frequencies of 5 GHz and above.
