We present our recent progress on the application of the Grad-Shafranov reconstruction technique to structures in the solar wind, utilizing multi-spacecraft data. The method, using both magnetic field and plasma measurements as input, is capable of generating a two and a half dimensional cross section of the magnetic field structure, as well as the plasma pressure and current density distributions. It has been applied to examine the magnetopause current sheet, magnetic flux ropes in the solar wind, and Flux Transfer Events. Utilization of simultaneous multi-spacecraft data facilitates the validation and interpretation of the results. In particular, we will report results from our study of structures near local heliospheric current sheet associated with quasi-steady-state magnetic reconnection, recently found from in-situ solar wind observations. We will produce quantitative two-dimensional reconstruction results to further aid in the interpretation of such events. The applicability, limitations, and new development of our current method, will be discussed.
