Emergency Services
A repair plan was formulated which involved a temporary stabilization that would allow traffic to once again move across the bridge. The columns under the west roadway were the ones tilting and the contractor J.D. Eckman of Atglen, PA wanted to make sure the superstructure as well as the involved columns did not move any farther before and during the construction of new columns under the substructure. The plan was to take 3″ diameter steel dywidag bars and attach them to the substructure from the east pier to the tilting west pier. These were placed on both sides of the columns and remained in place during new column construction and the jacking of the bridge. Kelken’s Keligrout 101-P high strength anchoring material was used to secure the dywidag bars in place during the emergency repair.
