Conejo Viaduct


The 2,000 foot Conejo Viaduct will carry high-speed trains over the existing BNSF rail line, Conejo Avenue, and Peach Avenue.


From Conejo Avenue to Clarkson Avenue, west of State Route 43 in Fresno County


Ironworkers at the Conejo Viaduct continue to assemble/fabricate 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. By the end of August 2020, all column rebar cages should be fabricated and placed.
