<br />Steel pipe liner will be installed along with shotcrete and rock bolts in various repair areas,
<br />Existing concrete lined sections will be repaired and stabilized. Once this is complete,
<br />approximately 800 cubic yards of rock will be removed from a 400-foot section where the
<br />collapse occurred, and that portion of tunnel will be rehabilitated,
<br />
<br />A temporary rail system will also be installed from the west portal, and repairs and bracing work
<br />will be completed on existing timbered supported sections, Portions of the west tunnel will be re-
<br />mined and rehabilitated with steel supports, A trash rack and steel door will be constructed at
<br />the east entrance, and the downstream deflection wall will be repaired.
<br />
