MOS-2 involved several extensions costing a combined $1.2 billion. The first extension as part of MOS-2, which brought the light rail system southward to 22nd Street in Bayonne, was opened on November 15, 2003. It also involved extending the line west and north of Hoboken Terminal into Weehawken. The line was completed to Lincoln Harbor on September 7, 2004, and to Port Imperial on weekends only on October 29, 2005. The line was extended from Port Imperial to Tonnelle Avenue in North Bergen on February 25, 2006, and light rail vehicles began running seven days a week to Tonnelle Avenue. Bus service on connecting routes was modified so that there would be more direct connections to Hudson–Bergen Light Rail stations. The extension to southern terminal at 8th Street opened January 31, 2011, at a cost of $100 million.
