We are carrying out the Sloan Bright Arcs Survey (SBAS), an ongoing systematic search for bright, strongly-lensed, high-redshift galaxies in samples of SDSS luminous red galaxies, clusters, and interacting/merging galaxy pairs. So far we have spectroscopically confirmed 20 lensing systems, with source galaxy redshifts z = 0.4 - 2.9, and 10 of these are among the brightest known z > 1.8 lensed galaxies. Here we will describe our search program and our sample, as well as our results on lens system modeling and source galaxy properties, derived from our optical and IR follow-up observations using ground- and space-based telescopes, including APO, Mayall, WIYN, Gemini, and HST.
