K Line Northern Extension
Expanding fast, reliable rail service from the E Line north to Hollywood with new connections to four Metro rail lines and key destinations
Metro is planning an underground extension of the K Line from the E Line north to Hollywood. The new rail service will connect with Metro’s B, C, D, and E Lines, serving six of LA’s busiest bus corridors and improving access to jobs, healthcare, and entertainment. Environmental review is underway.
Status
Metro is completing additional environmental analyses and engineering work in response to community feedback received during the Draft Environmental Impact Report (EIR) comment period, which closed September 20, 2024.
In 2025, Metro prepared new technical reports and hosted meetings to share findings on tunnel safety, property considerations, and potential refinements in the Mid-City area.
Community input collected throughout these engagements will inform Metro’s Winter 2025/26 staff recommendation to the Board of Directors on the selection of a Locally Preferred Alternative (LPA) and the next steps for the K Line Northern Extension Project.
Project StoryMap
Metro’s updated Summer 2025 Story Map summarizes findings from the Mid-City Additional Alignment Analysis, Tunnel Safety, and Property Considerations reports that respond to community feedback raised during the Draft EIR period.
New Published Reports
In August 2025, Metro released three technical reports: Mid-City Additional Alignment Analysis, Tunnel Safety, and Property Considerations.
West Blvd Alignment Option
Following the recent community meetings, Metro published the West Boulevard Addendum to Mid-City Additional Alignment Analysis Report, which outlines potential refinements to the West Blvd alignment to further minimize potential tunnel easements in Wellington Square.

Frequently Asked Questions
The K Line Northern Extension (KNE) project would extend rail service from the Metro Expo/Crenshaw Station north to the Metro D Line (Purple) stations currently under construction on Wilshire Bl, the Metro B Line (Red) at Hollywood/Highland Station, and potentially to the Hollywood Bowl. It would serve many communities, including the LAX area, South Los Angeles, Inglewood, South Bay, the Crenshaw Corridor, Mid-City, Central Los Angeles, West Hollywood, and Hollywood, allowing for further connections to points north in the San Fernando Valley via the Metro B Line (Red). This project would improve connectivity with Metro’s rail and bus network by linking four Metro Rail lines and six of the top 10 busiest bus lines in LA County. KNE would also connect major destinations, such as population, activity, and employment centers. The project is located in the cities of Los Angeles and West Hollywood.
- Leverage the high-volume east-west rail network to provide new north-south connections and close a regional network gap
- Increase the efficiency and convenience of transit trips by providing faster and more direct service
- Reduce how far and how often people need to drive (Vehicle Miles Traveled), which helps cut down on greenhouse gas emissions
- Maximize access to jobs, housing, and opportunity
- Improve mobility for transit-dependent residents
- Expand mobility with a fast rail option: providing ~47,100 to 59,600 daily trips,
- Attract new transit riders: serving ~11,400 to 15,100 new riders daily,
- Reduce auto use: approximately 127,500-135,500 vehicle miles traveled daily, and
- Create jobs: estimated 8,300 to 10,100 jobs during construction
Metro is leading the planning and environmental review for the project under the California Environmental Quality Act (CEQA). As part of this effort, Metro prepared and released a Draft Environmental Impact Report (EIR) for public review in July 2024. Metro hosted three public hearings and a community meeting during the 60-day public comment period and received approximately 1,300 public comments on various topics ranging from support for project and alignment preferences to questions about design, funding, schedule, and concerns on tunneling, property impacts, and construction disruptions.
Throughout summer and fall 2025, Metro shared the findings from these reports through a series of in-person and virtual community meetings, providing opportunities for Mid-City residents to review technical materials, ask questions, and submit feedback. Community feedback collected during this engagement period will help inform the staff recommendation to the Metro Board on a preferred route and next steps for the project.
The Metro Board is the decision maker for all Metro projects and will be asked to select a locally preferred alternative, called the LPA. Metro staff will make a recommendation to the Metro Board based on multiple factors, including the environmental impact findings from the Draft EIR, project objectives, technical analysis, benefits, costs, and community support and feedback.
The project has $2.24 billion from Measure M, a half-cent sales tax that funds several transportation projects/programs. The value of these funds increases with inflation. The funding identified in Measure M is not enough to construct the project. Measures M funds become available in 2041, which marks the earliest possible date for construction to begin barring additional funding sources. Metro will continue working with project stakeholders to explore additional funding sources.
As noted above, Measure M funds become available for construction in 2041 with a goal of opening between 2047 and 2049. The construction schedule would vary based on the alignment selected by the Metro Board, funding availability, phasing, and the construction delivery approach.
Metro notifies the community about the Project, community events, and public meetings in a variety of methods depending on the upcoming meeting or update, which may include email, door-to-door flyers, direct mailing, Project website updates, bus ads, social media, Metro’s The Source blog and local news media. The best method to stay up to date on the project is to join our email distribution list by signing up here.
All comments and feedback on the project during the environmental phase will be summarized and published on Metro’s website to be available to the public and decision-makers alike. Metro will share community feedback received with the Metro Board at all project milestones. These comments will be reviewed by the Metro team to inform the project development process.
