Similar to the Conejo Viaduct in Fresno County, the Tule River Viaduct will be comprised of a viaduct and pergola structure that will take high-speed trains over the BNSF rail lines. Currently, crews are working Friday thru Sunday between 8 p.m. and 4 a.m. to place the 264 pre-cast concrete girders needed for the pergola. On any typical night, crews can place between 8 and 10 girders. To date, 102 girders have been placed. Located in Tulare County, the structure will be more than 3,500 feet long.
