LA Bus Lanes

Bus lanes: LADOT and Metro striping, checked against Streetsblog LA's bus lane tally (Aug 2024), plus a few stretches added by hand; each tooltip names its source. South Bay, Pasadena and most of East LA were checked and have none, so blank there means none installed.

Future bus lanes: from Metro, LADOT, Caltrans and city plans, with statuses as of Sep 2026. Green dashes are under construction: work has started. Green dots are planned: adopted by a city or by Metro's board, or funded, and not started; several have no start date yet, as their notes say. Violet dots are proposed: not approved. The miles under each key are street miles along the lanes.

Rail and BRT (bus rapid transit): Metro and Metrolink schedule data in the GTFS format. Metro is in its own line colors, Metrolink in teal. The G and J Lines are drawn along their whole route, including where the J Line runs in traffic.

Mobility Plan (Measure HLA) (off until checked): the streets the City of Los Angeles's Mobility Plan 2035 marks for transit priority, from the City's GeoHub. A designation for transit priority, not a commitment to build bus lanes; city of Los Angeles only. Measure HLA is Healthy Streets LA. The share under the key is how much of that network has a bus lane within about 80 feet, built today or, with Future bus lanes checked, planned or under construction, and proposed, each counted once.

Arterials (off until checked): named trunk to tertiary roads with three or more through lanes in a direction, from OpenStreetMap lane tags (Sep 2026). Where tagging is patchy, short gaps are filled in; a corridor's tooltip gives its tagged share. Lengths are centerline, about 650 miles in all. Dotted peak-hour 3rd lanes are hand-curated from LADOT's parking-restriction roster.
