Looking south toward the Laurel Creek Bridge. Escape Ramp #3 is on the right side of the road, and there is an optical illusion involving the escape ramp. Although it appears in this photo that the ramp runs uphill, it actually is nearly flat with a 0.5% grade. The mainline runs toward the foreground on a 5% grade, which causes the ramp to appear to run uphill. The aggregate is already down on this portion of the road. Photo taken in June 2001.
