Millimeter-wave continuum and CO spectral line observations of SS 433 and the IRAS-detected infrared objects in the vicinity of SS 433 are reported. The 90 GHz flux from SS 433 was 0.087 + or - 0.037 Jy, consistent with an extrapolation of the lower frequency radio power-law spectrum. A 203 GHz upper limit for SS 433 is determined. Upper limits only were derived for two of the infrared objects at 90 and 203 GHz. The (C-12)O spectral lines from four of the infrared objects to the west of SS 433 were detected in the same velocity range as the western optical filaments and the nearby H II region S74. The masses and H2 column densities derived from the (C-12)O and (C-13)O lines are consistent with dark molecular clouds. It is suggested that the infrared sources and S74 are part of a gas complex in front of SS 433 and W50.
