Abstract: We report trigonometric parallaxes for the high-mass star forming regionsG35.20-0.74 and G35.20-1.74, corresponding to distances of 2.19 +0.24 -0.20kpc and 3.27 +0.56 -0.42 kpc, respectively. The distances to both sources areclose to their near kinematic distances and place them in theCarina-Sagittarius spiral arm. Combining the distances and proper motions withobserved radial velocities gives the locations and full space motions of thestar forming regions. Assuming a standard model of the Galaxy, G35.20-0.74 andG35.20-1.74 have peculiar motions of ~13 km-s and ~16 km-s counter to Galacticrotation and ~9 km-s toward the North Galactic Pole.
