LA Bus Lanes

Blue corridors come from OpenStreetMap lane tags (September 2026): named trunk to tertiary roads with three or more through lanes in a direction. Turn-only lanes are left out where OSM marks them; bus lanes count. Where a bus lane, busway, peak-only lane or not-yet-built lane runs along a corridor, its blue is hidden under it, so the two never share a stretch of road. Where tagging is patchy, short untagged gaps between qualifying stretches are inferred; a corridor's tooltip gives its tagged share.

Each line is one connected street, counted once where it is divided. Its lane figure is the typical count along it, and its length is centerline length. About 650 miles in all.

Bus lanes are LADOT/Metro as-built striping, cross-checked against Streetsblog LA's bus lane tally (Aug 2024), plus hand-verified additions (Florence Av, Culver City, Long Beach's 1st St transit mall, Westwood Plaza at UCLA), Lincoln Bl from a regional inventory (Big Blue Bus Rapid 3's lanes, north to Pico Bl, where the route turns, and south to Grant Av) and Santa Monica Bl's eastbound lane from Ocean Av to 5th St. South Bay, Pasadena and most of East LA were checked and have none installed — blank there is a verified absence, not missing data. Wilshire's eastbound lane at the VA (Bonsall to San Vicente) is not drawn: it is out of service while the D Line's VA station is built (opening fall 2027).

Metro's G Line and J Line, which run on busways and ExpressLanes, are under Rail and BRT below.

Green and violet lines are future bus lanes, from Metro's Speed & Reliability map, the NoHo–Pasadena BRT's final EIR, LADOT's Sunset East design, Caltrans' Lincoln Bl study and the bus lanes in Metro's 2024 federal grant (Broadway, Norwalk, El Monte) and the San Gabriel Valley BRT's quick-build segments, LA's Valley Bl, Westwood Bl and South Broadway projects, the Westside Cities' Westside Bus Connection and Santa Monica's Santa Monica Bl Safety Study (adopted May 2026, due before the 2028 Games), with statuses re-checked in Sept 2026. Green dashes are under construction; green dots are planned (approved and funded, not started); violet dots are proposed (still in outreach or design, with no approval yet). Vermont's quick-build lanes and its BRT are one project now, all planned. The NoHo–Pasadena BRT is drawn only where it gets its own lanes, and Burbank's lanes are on hold in a dispute with Metro. Untick them under Layers to hide them.

Peak-only 3rd lanes are hand-curated from LADOT's parking-restriction roster; LA publishes no per-sign dataset.

Rail and BRT is LA Metro's rail lines and stations, its G Line and J Line bus rapid transit (the G Line, including the section closed for construction, and the J Line from El Monte to San Pedro) and Metrolink's lines and stations, from each agency's GTFS schedule data: Metro in its own line colors (the G and J included), Metrolink in one gray. The G and J are drawn along their whole route as scheduled, so the J Line also shows where it runs in general traffic, downtown and in San Pedro.

Transit priority streets (off until ticked) are the Transit Enhanced Network of the City of Los Angeles's Mobility Plan 2035, from the City's GeoHub: the streets the plan designates for transit priority, drawn as thin, muted teal lines so the bus lanes lead. Measure HLA (Healthy Streets LA) ties building those improvements to street repaving. They show what is planned, not what exists, and cover the city of Los Angeles only. The share under the key is how much of that network's length has a bus lane running along it (within 25 m, either direction), built today or, with Future bus lanes ticked, planned; it follows those two boxes.
