This month, ironworkers at the Conejo Viaduct continue to assemble rebar cages that will be used to form the columns of the viaduct. The rebar cages are then lifted and placed in cast-in-drilled-holes (CIDH) bents to provide future support of the structure. On the east side of the BNSF railroad, 26 columns will be needed for the structure.
On the west side of the BNSF tracks, 18 of the 24 columns have been erected. Crews are now working on pouring concrete to form the column flares, the portion of the column that supports the structure. All column rebar cages should be fabricated and placed in the coming weeks.
