Thawing of Perpetually Frozen Silt on Alaska Highway; Three Temporary Bridges Across the White River. Original caption: 44-867: Utah Construction Co.'s daily supply convoy while passing through the "Grand Canyon" of the Alaska Highway pushed the flowing mud ahead of it to the drainage ditches thus exposing more ground to the thaw. Each day the convoy drivers found that the Alaska Highway had dropped a little further down between the two banks of frozen silt. Original caption: 44-868: All three of the temporary bridges across the White River may be seen in this photo. The one in the foreground
Thawing of Perpetually Frozen Silt on Alaska Highway; Three Temporary Bridges Across the White River. Original caption: 44-867: Utah Construction Co.'s daily supply convoy while passing through the "Grand Canyon" of the Alaska Highway pushed the flowing mud ahead of it to the drainage ditches thus exposing more ground to the thaw. Each day the convoy drivers found that the Alaska Highway had dropped a little further down between the two banks of frozen silt. Original caption: 44-868: All three of the temporary bridges across the White River may be seen in this photo. The one in the foreground and the one in the distance were built by the Elliott Co. and the one over the channel which is dry at the present time was built by the Army. Several bents of this army bridge were replaced by Elliott Co. after the summer floods. The permanent bridge site is at the mouth of the canyon. Photos by Pinkstaff, August, 1943. State: Alaska.
