Throughout the spring and summer, crews have placed 246 of the needed 248 pre-cast concrete girders for the pergola section of the Conejo Viaduct. To the south of the pergola, crews have tied rebar and placed concrete to form portions of an intrusion protection barrier – or IPB wall – that will allow high-speed trains to travel safely in the proximity of the BNSF railroad tracks.

More than 12,000 cubic yards of concrete have been placed to date to form the IPB wall that spans more than 3,400 feet wide, 40 feet tall, and up to five feet thick. When complete, it will help provide added safety between the high-speed rail and freight rail lines.
