Pretty sure I've seen it posted as a problem area before on this forum, but I-465 around Indianapolis is notorious for this as well, especially the northeast quadrant. Have literally had to go down to 30 MPH to keep the bounce under control, and have made a commitment to finding another way around Indy when we head south on any trips (home is 30 miles north of Indy).
