Sioux Falls Transit has several options. The closest, which has two buses running every 1/2 hour is the corner of 11th & Menlo. This is 1 block East of Grange, & 3-4 blocks North. There is a stop at 18th & Menlo also. Another at 18th & Grange, & 21st, & Grange, which has a shelter. I used to live at 810 S. Grange. The hospitals are the reason there are so many options in that local.
Hope this was of help.
