Vermont Avenue's southern point is just north of San Pedro at a five-point intersection with Anaheim Street, Gaffey Street and Palos Verdes Drive. After a short distance, Normandie Avenue branches off due north while Vermont turns northeast towards its intersection with Pacific Coast Highway (PCH). Afterwards, it travels roughly in a straight line north for 22 miles (35 km), parallel to the Harbor Freeway (I-110) to the east. North of PCH, it passes through the unincorporated area of West Carson before crossing the San Diego Freeway (I-405).
Between a point south of the intersection with Artesia Boulevard/western end of the Gardena Freeway (SR 91), and El Segundo Boulevard, Vermont marks the eastern boundary of the City of Gardena. At 164th Street in Gardena, Vermont widens from a four-lane thoroughfare to a six-lane road with a wide median. From 164th Street, an abandoned railway runs through the median to a point just north of Redondo Beach Boulevard, afterwards the median becomes tree-lined. From 88th Street to Gage Avenue, Vermont Avenue includes adjacent frontage roads. North of Gage, Vermont thins down to 4 lanes.
Gardena Line 2 between Interstate 105 and the Harbor Gateway Transit Center, Torrance Transit Line 1 between Gardena Bl and Carson St, and Metro Line 205 to PCH.
Metro lines 204 and 754 use 60-foot (18 m) NABI & New Flyer buses (9500-9594) & (8700-8834)
Metro is planning to rebuild the roadway between the Sunset B Line station and 120th Street. Initial plans call for a bus rapid transit line to operate along the corridor. In the future, Measure M funding is expected to become available for an extension of the B Line subway down Vermont Avenue at least as far as the neighborhood of Athens (just south of the 105 Freeway), possibly as a combination of both underground and elevated heavy rail.[2][3] Bus rapid transit implementation is expected as part of the Twenty-eight by '28 initiative, in anticipation of the 2028 Summer Olympics. Rail funding is planned for 2067. The service was dubbed the R Line in 2018,[4] though line names are tentative until opening.
