Norwalk Transit operates a connector shuttle bus service between the Norwalk/Santa Fe Springs Transportation Center and the Metro Green Linestation in Norwalk. The rail feeder service implemented by Norwalk Transit provides direct interconnectivity between rail stations (Metrolink – commuter rail and Metro Green light rail).
There have been persistent proposals for an 2.5 mile eastward extension of the Los Angeles Metro Green 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 2001 Los Angeles County Long Range Transportation Plan (LRTP) lists funding priorities to build through year 2025 – the Green Line east extension is not a funded project in the MTA LRTP and is unlikely to receive funding under this plan.
