K Line Northern Extension
proposed light rail transit corridor in Central Los Angeles

The K Line Northern Extension, formerly known as the Crenshaw Northern Extension, is a planned Los Angeles Metro Rail light rail extension connecting Expo/Crenshaw station to Hollywood/Highland station in Hollywood. The corridor is a fully underground, north–south route along mostly densely populated areas on the western side of the Los Angeles Basin; it would be operated as part of the K Line. Los Angeles Metro is prioritizing the project along with pressure from the West Hollywood residents. Construction is slated to start in 2041 and begin service by 2047, although local officials are attempting to accelerate this timeline using Enhanced Infrastructure Financing District (EIFD).
On July 23, 2024, LA Metro released the draft of the Environmental Impact Report (EIR) for the K Line Northern Extension, putting the price tag of the project between $11 billion and $14.8 billion (including a 40% contingency cost).
Overview
Los Angeles Metro budgeted $2.33 billion from Measure M. The Crenshaw/LAX corridor Line was a corridor designated for public transit. It became a light rail line between the C Line and the E Line, with planned connections to LAX. After almost ten years of construction, the K Line, as it was named, opened in 2022. A northern extension could connect with regional job centers and tourist destinations, such as Cedars-Sinai Medical Center, Beverly Center, The Grove, Farmers Market shopping area, and LACMA. The West Hollywood areas are also in the projected routes, Melrose and the Sunset Strip within walking distance.
Original planning
The original plans for the Crenshaw Corridor project connected Wilshire Blvd to LAX. However, during the environmental review, Metro determined that if LRT were selected as the preferred mode, the cost for the entire route would exceed the project budget. In December 2009, the Metro Board decided on LRT as the preferred mode; as a result, the part of the corridor north of Exposition Boulevard was deferred until funds became available.
