High extinction towards the Galactic plane is a major obstacle to study the far side of the Milky Way. In order to explore the Galaxy, low extinction windows such as the Baade’s window in the bulge have been used to study its stellar content and structure. We present now the analysis of windows of low extinction towards the Milky plane recently discovered by the VVV Survey. These windows at Galactic longitudes |b|<1 deg allows one to explore the far side of the Milky Way right in the plane and to study the structure of Galaxy by analyzing the distribution and proper motion of their stellar content. VVV red clump stars within these windows are used to map the far side of the disk and present evidences of the the spiral arms across the Milky Way.
