The Magellanic Bridge is a physical connection between the Large Magellanic Cloud and the Small Magellanic Cloud. It is known to contain a young stellar population that was probably formed in local molecular clouds. High column density of neutral hydrogen (H I) in the Magellanic Bridge also suggests it could be a local counterpart of Damped Lya (DLA) systems, mysterious H I gas reservoirs at high-z . We carry out an analysis of VLT/UVES spectroscopy of multiple sight-lines of the Magellanic Bridge toward QSOs/AGNs behind it, covering Ca II H, K lines and Na I D1, D2 lines. These measurements are essential to evaluate physical conditions of gas clouds in the Magellanic Bridge along multiple sight-lines derived from the photoionization models. The data provide the unique opportunity to study the three dimensional structure of a DLA analog in our Local Group.
