The structure of the Sagittarius spiral arm is studied through the combination of radio observations, near-IR photography, spectroscopy, and IR photometry in the direction of l = 305 deg, b = 0.2. An unambiguous identification of 11 sources as M stars ranging in distance from 1 to 3.8 kpc has been accomplished, and many of the 72 sources studied have been found to be members of two new galactic clusters. Three sources are identified as the IR components of OH/H2O masers.
