Cerritos Channel Transmission Relocation Project

Expose as Block

With the new Gerald Desmond Bridge being built at the Port of Long Beach, the purpose of the Cerritos Channel Transmission Relocation Project (CCR) is to raise the electric transmission and telecommunication lines crossing the Cerritos Channel to accommodate taller container ships entering the channel.

The six existing towers supporting the lines across the Cerritos Channel are located near Pier S and between Piers A and B. These towers are almost 100 years old; therefore, SCE will be replacing them with two updated lattice steel towers. The towers will also be in new locations to allow continued 66 kilovolt (kV) service to SCE’s customers while the new towers are being built:

  • The new south tower (M0-T2X) will be located on Pier S
  • The new north tower (M0-T3X) will be built on SCE’s right-of-way (ROW) near Carrack Ave and Pier A Way

Four smaller, tubular steel poles will be added within SCE’s right-of-way near the new north tower (M0‐T3X) to serve as a transition point between the new conductor configuration at M0-T3X and the existing conductor at tower M0-T4.

Transmission Lines

The new towers will support new 66kV conductor, 12kV conductor, telecommunication cable, overhead ground wires, and Federal Aviation Administration (FAA) marking and lighting.

The existing 220kV circuits crossing the channel are being retired and the conductor and structures will be removed starting from the Long Beach Substation all of the way to the Harborgen Substation.

Structures and Foundations

Overall, six new structures (the four tubular steel poles and the two lattice steel towers) will be installed on top of new foundations.

With the removal of the 220kV circuit up to the Harborgen Substation, six old lattice steel towers will be removed. The foundations for the M0-T2 towers, located in the channel, will be removed after completion of the relocation work. The foundations at M0-T3 will be remain in place.

Phase I versus Phase II

  • Phase I of the CCR project includes all work to allow taller container ships to enter Cerritos Channel (replacement and relocation of towers and lines).
  • Phase II of the CCR project only includes the removal of the underwater foundations near Pier S.

As of January 2019, SCE’s construction contractor is working with the geotechnical team to finalize foundation designs. In February, the 220kV tower removal will start in the Long Beach Substation.
