VLBI and VLA observations of the nuclear and overall radio structures are presented for eight quasars possessing large double-lobed radio emission. On milli-arcsec scales, the nuclei of five sources show an asymmetric (core-jet) morphology, one has a symmetric appearance one is unresolved and one is too weak to allow a reliable determination of its structure. Total intensity, polarization and spectral index maps of the associated kpc-scale emission were obtained for six of the eight quasars. The inner and outer radio jet emission generally are well aligned and pointing in the same direction; in one source, the pc- and kpc-scale jet are oppositely directed. Jet velocities close to the hot spots were estimated for several quasars from the intensity of their hot spot emission. The velocity estimates were relativistic in all cases (ranging from 0.5 to 0.9 c).
