In fall 2008 crews will begin construction of the soldier pile wall, as seen above, to permanently repair the slide area. The wall will be constructed with beams that look like the letter "H," spaced about 6 feet apart from each other. Crews will fill the gaps with timber to form a solid wall. The beams will be driven 10 to 20 feet into the soil and anchored into the hillside with 40- to 50-foot long cable "nails."
This diagram shows a cross section of the temporary soil nail wall that crews have built along US 2. Crews built a 130 foot long wall, inserted 40 foot long nails into the hillside, and installed a new drainage system. This will help ensure that the road does not continue to sink and that we can keep this critical route open and safe for drivers while we design the permanent fix.
