Observations of long-period Cepheids between l = 294 and 331 degPhotoelectric and spectroscopic observations of long-period Cepheids, as well as 21-cm profiles in the directions of these young stars, are presented for the Crux-Centaurus-Circinus-Norma section of the Milky Way. The UBV data have been used to revise periods and light-curve parameters and ultimately to calculate the distances of these stars. From the spectroscopic information velocity estimates have been made. Finally, the stellar velocities have been compared with H I gas motions detected along the same line of sight. These results are briefly discussed with a view to understanding the spiral structure of the region.
