The J Line (formerly the Silver Line, sometimes listed as line 910/950) is a 38-mile (61.2 km) bus rapid transit line that runs between El Monte, Downtown Los Angeles and the Harbor Gateway, with some trips continuing to San Pedro. It is one of the two lines in the Metro Busway system operated by the Los Angeles County Metropolitan Transportation Authority (Metro).

The J Line offers frequent, all-stops service along the El Monte Busway and the Harbor Transitway, two grade-separated transit facilities built into the Southern California freeway system. The line was created on December 13, 2009, as part of the conversion of the facilities from high-occupancy vehicle lanes into high-occupancy toll lanes (branded as Metro ExpressLanes) that allow solo drivers to pay a toll to use lanes. The tolls collected have been used to operate the J Line and refurbish the old stations on the line.
As J Line buses travel along the El Monte Busway and the Harbor Transitway, they serve stations built into the center or side of the roadway. There is a 3.6-mile (5.8 km) gap between the western end of El Monte Busway and the northern end of the Harbor Transitway in Downtown Los Angeles, where J Line buses travel on surface streets, making a limited number of stops. Along the route, buses serve several of the region's major transportation hubs, including El Monte Station, Union Station, 7th Street/Metro Center station, Harbor Freeway station and the Harbor Gateway Transit Center.
In 2020, the line was renamed from the Silver Line to the J Line while retaining its route numbers and the color silver in its square icon as part of renaming all Metro lines.
Future developments[edit]
As part of Metro's NextGen Bus Plan, the agency had proposed discontinuing the J Line's route 950, which offers service to San Pedro.[20] Metro said the change would allow the J Line to transition to battery-electric buses and would improve the reliability of buses that operate between El Monte Station and Harbor Gateway Transit Center. Service to San Pedro would have been shifted to a new line between San Pedro and the Harbor Freeway station via I-110, with a peak-hour extension to Downtown Los Angeles.[21] The San Pedro neighborhood opposed the change, with citizens requesting that they also receive electrified bus service and maintain a one-seat ride to Downtown LA and El Monte. As a result, plans to end the J Line's service to San Pedro were put on hold indefinitely.[22] Metro has abandoned any public timeline regarding electrification of the J line, however the BYD vehicles that would be used are allegedly scheduled for delivery this year (2024).
