Church Avenue Grade Separation

Progress continues at the Church Avenue Grade Separation in the City of Fresno. Crews recently removed the formwork on abutment one, west of the high-speed rail corridor. Crews also placed more than 1,070 cubic-yards of concrete at abutment three, located on the east side of the high-speed rail corridor and existing Union Pacific tracks. Crews will continue foundational work including cast-in-drilled-hole (CIDH) pile installation in the coming weeks. When complete, the Church Avenue Grade Separation will consist of two structures. One structure will take traffic over the future high-speed rail and Union Pacific tracks and will span 340-feet long and 84.5-feet wide.

There are multiple utility relocations ongoing near the Church Avenue Grade Separation, including the installation of new sewer lines being installed under the BNSF railroad tracks. Crews are also working with Fresno Metropolitan Flood Control District to complete its largest jack and bore – a method of horizontal boring for utility construction – under the Union Pacific Railroad Tracks. Majority of the utility work is expected to be  completed this fall, and substructure work will begin shortly after. When complete, the Church Avenue Grade Separation will take traffic over the existing Union Pacific and BNSF train tracks, along with the future high-speed rail tracks.
