There have been persistent proposals for a 2.8-mile (4.5 km) eastward extension of the Los Angeles Metro C/K Line from its current terminus at Norwalk Station to reach the Metrolink Station at Norwalk. This project carries a proposed cost of $321 million for an aerial bridge, and a $360 million cost for a subway. Since an initial Environmental Impact Review (EIR) in 1993, there has been no solid progress for this proposal. The Los Angeles County Metropolitan Transportation Authority (Metro) 2009 Long Range Transportation Plan (LRTP) lists funding priorities to build through year 2040 – the C Line east extension is not a funded project in the Metro’s 2009 LRTP and is instead in the Tier 1 Strategic Unfunded Plan.
