This should better simulate what is seen visually.
These images were taken from very dark skies in WA but both Magellanic clouds were low in the sky.

Great pictures! These images show the region between the Clouds and the Gum nebula in Vela. However the LMC light bridge goes to the upper left corner, towards Atria and beyond. However, some subtle brightening might be seen along this path towards the south celestial pole. An interesting faint patch of nebulosity is visible in the borderland of Chamaeleon-Octans-Mensa, about the size of SMC. The light bridge should be brightest in the Apus area (just beyond the upper left corner). The images should have twice the field of view.
Brian Skiff informed me on December 19, 2009, that he had once seen an image of the LMC bridge taken with a "parking lot" (?) fish-eye lens at Las Campanas, Chile.
"Greetings Timo. The bridge from the LMC toward the galactic center that you describe is just what I saw on both of my trips to Las Campanas in Chile. It basically extends straight south from the LMC to the south celestial pole, then follows a great-circle approximately to the Norma starcloud (or, alpha TrA, as you say) --- it runs into the Milky Way, so you lose it much like the zodiacal band close to the Milky Way. I, too, have wondered why it is not mentioned anywhere that I know of. I remember once seeing an image taken at CTIO using what they called the "parking lot camera", a wide-field lens + CCD. This image showed the feature, but I do not know where to find that image again.
I do know it is not the "Magellanic Stream" from the professional literature: this is a radio-wavelength feature (neutral hydrogen, CO and other gases) that goes in a different direction and reaches into the northern hemisphere.
The Axel Mellinger composite all-sky images should show it,but I think his calibration "flatted" it out of the final images.
