Construction for Phase 1 of this project extended MUNI Metro light rail service six miles south from its current terminal at Fourth and King Streets. The line will cross the Fourth Street Bridge and run along Third Street and Bayshore Boulevard, ending at the Bayshore Caltrain Station in Visitacion Valley with 19 stops along its way. ISI performed all soils, concrete, masonry and welding-related quality control testing and inspection services for the general contractor. The work encompassed tracks, platforms, utilities, light poles and traffic signals. This phase opened for service in 2005.
