The Red Line is a heavy rail subway line running between Downtown Los Angeles via the districts of Hollywood and Mid-Wilshire to North Hollywood within Los Angeles where it connects with the Metroliner Orange line (bus rapid transit) service for stations to the Warner Center in Woodland Hills and Chatsworth. It is operated by the Los Angeles County Metropolitan Transportation Authority.
In 1995, during construction of the subway, a sinkhole appeared on Hollywood Boulevard, barely missing several workers and causing damage to buildings on the street. Subway construction was halted until the situation could be resolved. The contractor, Shea-Kiewit-Kenny, was replaced with a new contractor, Tutor Saliba.
