Based on a D.C. map that I have, to get to the Supreme Court Building on First Street NE, in Washington, D.C., to Capitol South, you will need to take 1st St. NE, to Independence Avenue SE. Then you need to turn on 2nd St. SE, and then again on C St. SE. Your last turn would be on 1st St. SE. It's only 6/10ths of a mile. It would be probably be faster to walk, then to drive.
