Workers install 96-inch sections that connect the
New Irvington Tunnel to the Bay Division Pipelines.

Old sections of the Bay Division Pipeline must be torn out to make way for new sections.

A worker welds sections of the new pipeline together.

Modifications are made to the tunnel’s rail and muck system. Materials and workers travel into the tunnel, and soils and equipment come out of the tunnel on a series of special rail cars.
