SAN FRANCISCO (BCN) — Demolition crews will begin removing the second of five truss spans on the old eastern portion of the Bay Bridge this weekend, Caltrans officials said.

The first 504-foot truss span was lowered onto barges in February and hauled to the Port of Oakland for deconstruction.

The next span will be lowered on Saturday and get transported to the port on Sunday, providing there isn’t heavy rain or strong wind.

The five truss spans covered about a half-mile of the bridge before it was decommissioned in 2013.

The first phase of removing the old bridge was completed last year with the demolition of the cantilever section and the connector to Yerba Buena Island.

Phase two includes removing the five 504-foot truss spans as well as 14 288-foot truss spans that extend to the Oakland shore.

The materials from the dismantled spans will be recycled.

Caltrans is also removing the piers between the truss spans and is seeking permits to implode them in the way it imploded the largest pier in November.
