We obtained SOAR telescope B and V photometry of 14 star clusters and 2associations in the Bridge tidal structure connecting the LMC and SMC. Theseobjects are used to study the formation and evolution of star clusters andassociations under tidal stresses from the Clouds. Typical star clusters in theBridge are not richly populated and have in general relatively large diameters(~30-35 pc), being larger than Galactic counterparts of similar age. Ages andother fundamental parameters are determined with field-star decontaminatedphotometry. A self-consistent approach is used to derive parameters for themost-populated sample cluster NGC 796 and two young CMD templates built withthe remaining Bridge clusters. We find that the clusters are not coeval in theBridge. They range from approximately a few Myr (still related to optical HIIregions and WISE and Spitzer dust emission measurements) to about 100-200 Myr.The derived distance moduli for the Bridge objects suggests that the Bridge isa structure connecting the LMC far-side in the East to the foreground of theSMC to the West. Most of the present clusters are part of the tidal dwarfcandidate D 1, which is associated with an H I overdensity. We find furtherevidence that the studied part of the Bridge is evolving into a tidal dwarfgalaxy, decoupling from the Bridge.
