Work on the Manning Crevice Bridge.
As of Tuesday, August 9, 2016
RIGGINS As work on the Manning Crevice Bridge continues, a second large crane arrived last week by way of Burgdorf and micropiles that form a key part of the base were finished. On top of the micropiles, a 20-foot tall concrete abutment will eventually be constructed, and on top of the abutment, a 75-foot tall steel tower will eventually be placed.
This week, workers are assembling a large crane on the south side of the Salmon River, and the lane for traveling past the south side crane is reduced in width to 10 feet.
Current work includes drilling ground anchors at the north abutment, excavation prep on the north slope for more ground anchors and assembly of the south crane.
