Accurate distances to supernova remnants (SNRs) are crucial in determiningtheir size, age, luminosity and evolutionary state. To determine distances, wechose three SNRs from the VLA Galactic Plane Survey (VGPS) for extraction of HIabsorption spectra. Analysing HI absorption spectra, $^{13}$CO emissionspectra, and HI and $^{13}$CO channel maps, kinematic velocities (or theirlimits) to the three SNRs were calculated. The three SNRs are probablyassociated with molecular clouds and the new distance to G$20.4+0.1$,G$24.7-0.6$ and G$28.6-0.1$ are $7.8 \pm0.5$ kpc, $3.8\pm 0.2 $ kpc and $ 9.6\pm 0.3 $ kpc, respectively.
