The Harbor Transitway (also known as the I-110 Express Lanes) is a shared-use express bus corridor (known as a busway or transitway) and high occupancy toll (HOT) lanes running in the median of Interstate 110 (Harbor Freeway) between Downtown Los Angeles and the Harbor Gateway Transit Center in Gardena, California. Buses also make intermediate stops at 37th Street/USC, Slauson, Manchester, Harbor Freeway, and Rosecrans stations. The facility opened for two-person carpools (high-occupancy vehicle lanes) on June 26, 1996, for buses on August 1, 1996 and was converted to HOT lanes as part of the Metro ExpressLanes project on November 10, 2012. The Harbor Transitway is utilized by the J Line, a bus rapid transit route operated by the Los Angeles County Metropolitan Transportation Authority. It is also used by Los Angeles Metro Bus, Dodger Stadium Express, GTrans, LADOT Commuter Express and Torrance Transit bus services, most of which only run during weekday peak periods. South of the Harbor Transitway, the Harbor Freeway also has two stations on the shoulder of the highway, Carson station and Pacific Coast Highway station which opened on November 18, 2000. History Construction The Harbor Transitway project built of new lanes (two in each direction) for buses and two-person carpools (high-occupancy vehicle (HOV) lanes) between Downtown Los Angeles and a new transit center in Gardena, California. The most visually striking part of the project were the 2.6 miles of viaducts that elevated the transitway directly above the regular freeway traffic. The project also included new stations in the median of the transitway at 37th Street/USC, Slauson, Manchester, Harbor Freeway, and Rosecrans along with the Harbor Gateway Transit Center (then called the Artesia Transit Center) located southeast of the Harbor Freeway/State Route 91 interchange and connected by a flyover ramp. South of State Route 91 to San Pedro, a section of the Harbor Freeway was widened from six to eight lanes. On this section of freeway, buses travel in the general-purpose lanes and make stops at new stations on the shoulder at Carson and Pacific Coast Highway. The project also built the off-highway Harbor Beacon Park & Ride in San Pedro, originally intended to be a transit center for the city. The project to widen the Harbor Freeway and build the Harbor Transitway was planned and constructed concurrently with the new Interstate 105 (Century Freeway), which was highly controversial and the California Department of Transportation (Caltrans) was
