Description

The Long Beach Lead Bridge over Dominguez Channel was part of the larger Alameda Corridor Project - a 20 mile railroad freight express line with service between the Port of Long Beach and the transcontinental railroad near downtown Los Angeles.

The bridge consisted of six spans of steel I-girder construction. The foundation consisted of 40 16-in CISS piles and 25 36-in CISS piles. In addition to the bridge, the project included approximately 1,500 ft of new track construction, permanent sheet piles, retaining walls, and various utility work. The majority of the excavated soil was contaminated and extensive testing was performed to determine the proper classification and disposition.
